Hi!

Recently I noticed my PC being loud since i stopped using headphones. I ran HWMonitor and these were the results

Mind you, these are the results after a good clean and new thermal paste layer - i used arctic silver 5. Yet these temperatures seem really high. Really need help determining a fixing this issue as i believe it's been going on for months and surprised it's lasted this long. Please help any way you can. Thank you.

CPU: i7 4790K 4.0GHz

    In addition: I usually power 3 Screens - 4k, 2k, 1080p. guessing that affects the gpu more but just in case it's helpful. Ask for anymore information you need

    • HighAndDry on 29/10/2018 - 13:51

      1. Use another program to see if it might be a sensor/software error, if you still get the same temps from different sensors/monitoring software, then:

      2. Check that you've re-applied and re-seated the CPU properly, because you shouldn't be getting these temps unless you're OC'ing like crazy or using a really really bad CPU cooler (even stock should get better temps than these) (or living in a rainforest?).

  • DarthAntz on 27/10/2018 - 14:15

    i have a similar spec PC to you. the i7 4790k is still an awesome processor. Check your fans are actually working by looking at the bios. i'd update/reflash the bios too.

    for some reason i have 2-3 cores running at 100 degrees also, but usually the first 2 cores (in HWinfo) say they are running fine.

    Ive had to reset my ram (pull the ram out and put it back in again) to fix a powering-up related problem.

    • ayad on 27/10/2018 - 14:22

      fans seem fine. all giving rpm values or should i be assessing it differently? how do i update/refresh the BIOS? is it within the BIOS menu?

      • DarthAntz on 27/10/2018 - 14:26

        search on the motherboard manufacturer website for a bios update and instructions on how to update the bios. sometimes you:ll copy onto a usb stick, other times you can find on the hdd. depends on the motherboard.

      • cameldownunder on 29/10/2018 - 09:18

        I am coming from the Laptop camp, and when I see temperatures that high ( I Normally do it earlier ) I know it's time to clean the Fans and the "exhaust" grid, as the fan are running just fine ( maximum rpm ) but there is no air circulating as everything is clogged by dust.

        you dont have a fan sitting on top of the CPU? This is what a CPU cooler is. often a big piece of aluminium and copper used to dissipate heat, with a fan blowing through it

        • ayad on 27/10/2018 - 14:30

          oh I thought it would be something on the back of the motherboard. I have attached images below take a look. I just call it a CPU fan which i took out cleaned. new thermal paste and reinstalled

            @ayad: The thermal paste layer has to be really really thin, otherwise it acts as an insulator. Just put 2 to 3 drops/blobs of it.

            If you have used a lot, I would recommend to clean the earlier paste and reapply.

      The CPU cooler is the one in the middle with Metal Fins, fan and Intel badge on it, the stock cooler.

    • ayad on 27/10/2018 - 14:30

      that first pic tho, looks like some sort of cooling can be installed on the back of the motherboard?

      • Hybroid on 27/10/2018 - 14:33

        No, you don't install a cooler at the back and that stock Intel cooler is crap. Get an upgrade and it'll make a world of difference. Either another dual fan air cooler or a closed loop water cooler if you fancy splurging.

        • ayad on 27/10/2018 - 14:34

            @ayad: Corsair H80i would be my recommendation and fit the radiator and dual fan setup to that rear fan. It'll work as a hot air exhaust very well. I have that running on mine 24/7 since 2013 flawless.

              @Hybroid: Thank you for those suggestions. Kinda of overwhelming lol. think I'll set a 50-75 budget. What do you think of cooler master hyper 212x as mentioned below?

              • Hybroid on 27/10/2018 - 14:52
                +1

                @ayad: Cooler Master Hyper 212X not a bad choice for the money but make sure it's a dual fan version as you will prefer a push/pull setup rather than single fan for better performance.

                Having said that, it will be blowing a lot of hot air into the case itself so you might want to get a higher performance rear exhaust fan to push that air out.

                Your CPU is a socket 1150 which is supported fine.

                I would still suggest a closed loop water cooling setup for better performance & no internal hot air circulation esp if gaming machine.

              • loropy9 on 27/10/2018 - 16:11

                @ayad: I have the 212 dual fan cooling an i78700. It is sufficient to keep the temps down with gaming.

                @ayad: Wouldn't really bother with a liquid AIO. Air coolers work just as well and are quite cheap, and you don't have to mess around with installing a big radiator on your case. I recommend the noctua NH-D15 or D15S if your case is too small or you don't have enough clearance for RAM.

              • argonbay on 29/10/2018 - 00:07

              • Hybroid on 27/10/2018 - 14:56

                @DarthAntz: Looks good, would definitely recommend a closed loop water cooling setup. Check reviews of that EVGA vs the smaller H55 or H60 model and take your pick. You may need to pick up an additional fan if you can fit it in so it's on both sides of the rad.

          Calm down here. There's no reason OP needs to upgrade his CPU cooler. The stock one is designed to do the job perfectly fine.

          My guess is when you removed and reseated it there's now a bad thermal connection. Clean and reseat it.

    • O15 on 28/10/2018 - 13:24
      +15

      I haven't read this whole thread, so I don't know if anyone has already mentioned this.
      However, as soon as I looked at your pictures, I could see that your cooler is not correctly mounted.

      The first picture (the back of your motherboard) shows that the top left push-pin (or top right, if you are looking at the front side of the motherboard) is not securely in place.
      If your cooler does not have the correct amount of pressure against the CPU, you can expect temperatures like what you are seeing.

      The Intel stock cooler (especially the later designs) are complete rubbish, an improperly mounted one is even worse.

      EDIT: Guess I should have looked one comment down… Already pointed out.

      • xylarr on 29/10/2018 - 17:14

        Definitely this. Good catch. Sometime you have to push quite hard to get the push-pins to click in place.

    • Banville on 28/10/2018 - 23:13

      One thing that is really worth checking is to make sure the CPU cooler is mounted correctly. I've dealt with 4 different computers where the user hasn't clipped it in properly. There is a poor rotation clipping mechanism in the intel cpu cooler.
      The problem seemed to be that they thought it was clipped in and I assume the thermal paste made it seem like it was held in place when the pc was on it's side but when they put it upright it comes unstuck (because the clip wasnt engaged).

    • jonathonsunshine on 30/10/2018 - 17:38

      I've seen way worse cabling, including PCs I've built myself. Never overclocked except just to experiment though and certainly never hit 100° so I've not worried about it in the past.

  • Cartman2530 on 27/10/2018 - 14:37

    One of the plastic pins of the CPU cooler isn't in properly. See your 1st photo, the top left one.

    Pull the cooler off, check there isn't too much thermal paste, as too much can cause problems too, and re-seat properly.

    Don't overclock as the stock intel coolers can barely handle a stock CPU let alone an overclocked one.

        Has that fixed your issue? My mate did the same thing when reapplying some new thermal paste and ended killing the cpu (and perhaps motherboard? It BSOD'ed until it didn't turn on again and he didn't find out about the badly seated cpu cooler until it went to the shop).

    Less is more with thermal paste. Too much and it won’t do its job. You’re not spreading Nutella.

    • Manh on 28/10/2018 - 17:07

      As long as the paste covers the whole IHS. Using the thin spread method is the safest way to guarantee that. A tiny blob in the centre of the IHS method can result in not all of the IHS being covered and leaving some hotspots. If using good thermal paste, too much is not a problem.

      Gamers Nexus tested the "too much paste is bad" myth. Note: They used good thermal paste.

        If using good thermal paste, too much is not a problem.

        Unless it gets on the mobo and kills it. And your 'thin spread' method potentially lets air bubbles remain between the CPU and the cooler.

        One rice-grain sized blob in the middle. Place CPU cooler on top and secure down evenly. That's it.

    If you are happy with default clock speeds, you could try undervolting within the bios. Probably only worth 5 degrees, though.

    • ayad on 27/10/2018 - 16:28

      do you know how to use it? got a laptop locked at 1.6GHz and low temps. want to remove that and allow it to run at 2-2.2GHz base. what do i change since it's not strictly just undervolting

      • [Deactivated] on 27/10/2018 - 16:59

        That's overclocking, and will depend heavily on the features of your motherboard and BIOS. Laptops often don't have great support. :( I would just check your BIOS at the boot sceen. Laptop CPUs often don't overclock as well from the factory as desktops and obviously cooling is more difficult.

        • ayad on 27/10/2018 - 17:04

          yes definitely understand but consider this case: the i58250U has an unnecessarily low base clock on purpose to prolong battery life and runs at very low temperatures. It has a turbo boost feature that kicks it up to 3.4GHz momentarily before thermal throttling. It's a a realtively common issue with Lenovo thinkpad E480 and one of the Yoga series. I just need to know how to remove this limit and what to change + in what increments while monitoring temps to achieve a higher safe base clock coz 1.6GHz is way too low.. love that laptop overall but the CPU is a big let down and almost makes the R550x GPU a waste too (not 100% sure if related tbh)

          • Pyrock on 28/10/2018 - 13:43
            +1

            @ayad: If it is thermo throttling on turbo then it is already doing its max speed while under max temps. Increasing the base clock won't really do much as you will still likely only get to about the speeds that you thermo throttle to.
            Even if your mb on the laptop fully supported overclocking you would still lose the turbo boost feature as overclocking locks the clock speed at a certain rate (altho some mb do allow you to have a small window for the clock speed to move within)

            • idonotknowwhy on 28/10/2018 - 17:21

              @Pyrock: Agreed. Overclocking would only increase idle temperatures and battery life, shortening the lifespan of the laptop.

            • ayad on 28/10/2018 - 18:12

              @Pyrock: to clarify thermal throttle kicks in at 3.40Ghz after a couple minutes but it's base clock is 1.6GHz. So why wouldn't OC to e.g. 2.02-2.2GHz increase its overall performance considering it's turbo boost and throttle kicks in when doing something quite demanding?

              It definitely feels a bit slow just opening programs.

              • Pyrock on 29/10/2018 - 13:23
                +1

                @ayad: Im not sure that you are understanding what overclocking will give you and what it will take away.
                If you OC to 2.2GHz, then you will never go any higher than 2.2GHz (wont be able to turbo)
                Yes this is higher than your base clock, but your CPU was only turboing when it needed the higher clockspeeds ie it was sitting at its base clock of 1.6GHz, then going higher than 2.2GHz when it was running anything that required it to run faster.

                If you arent handling the temps then overclocking will likely only decrease your overall performance rather than increase it in this situation. Overclocking is only ever beneficial if you have plenty of temperature headroom to play with eg if you used watercooling or a beefy air cooler that brought temps right down to say 40degrees, then you have another 40degrees about to safely play with for overclocking.

                For your laptop, if you dont want to try anything as drastic as opening it up and using your own thermal compound on the CPU or even delidding, then i would suggest using the bios or other software to make the fan curves more aggressive so that it doesnt thermal throttle as much. Yes this will be louder but hopefully it shouldnt thermal throttle.

      Make sure the CPU heatsink has cooled down properly before you reapply paste. The amount is about OK but the coverage is poor as you can see.

      Should be about a pea sized amount that spreads over the entire heatsink. There's videos online on how you can spread it and endless debate about which method is best: https://www.pugetsystems.com/labs/articles/Thermal-Paste-App…

      Definitely push down the screws all the way in so it's a level fixing on all corners.

        ok so reinstalled everything. base temp 45 degrees. regular load 60-75 degrees. opening 50 tabs pushed it to 90-100 again. I will invest in a new CPU cooler soon after i check BIOS, undervolt etc and see what affect that has. Thank you for the help.

            @Hybroid: so every time i open a new tab to a website e.g. middle click youtube, i hear the fan momentarily wind up and down. is that too much response for a single tab?

              @ayad: YouTube videos can actually be pretty CPU intensive for older CPUs depending on what resolution you are watching at. Worry more about the temp of the CPU rather than fan speeds.if temps are fine then the only issue is how loud it is.
              You can try adjusting the CPU fan curves if you want to be more or less aggressive on cooling. Should be able to do this in bios if you don't have any software to do it.

          Right now it's not the CPU cooler that's the problem. It's that you have no bloody clue what you're doing. You'd get better temps with even a stock Intel cooler (and yes, those are shyte, I know.)

          Don't DIY stuff (unless you're happy with risking killing it) unless you've done your research and know what you're doing. I'd try this for now:

          1. Take the CPU cooler off (go google/youtube how to do that without breaking something).

          2. Clean the current thermal paste off both the CPU and the CPU cooler. Use isopropyl alcohol NOT WATER for this.

          3. Place one rice-grain sized blob of thermal paste in the middle of the CPU die (google if you don't know how big a rice-grain is).

          4. Place the CPU cooler onto the CPU die evenly (meaning flat) and with moderate force only.

          5. Secure the CPU cooler down property.

          Then run all the benchmarks and tell us what you see. Also while you're in there, use a can of compressed air to clean out the cpu cooler fan, dust the motherboard, and your case fans/vents.

          ALSO JUST TO CONFIRM: THAT'S THE STOCK COOLER THAT CAME WITH YOUR CPU, CORRECT? It looks…. off.

            @HighAndDry: I know what I'm doing. I built it from scratch a few years ago. I reapplied thermal paste and resat the cpu cooler and it helped quite a bit. Not hitting 100dc anymore. Max I've seen today is 75dc Invested in a liquid cooling system in the end with plans to OC. Anyways, appreciate your help tho.

            Yes stock intel I haven't changed it.

              @ayad: Look - I've built PCs etc, and even I have to basically re-watch all the basic tutorials if it's been over a year since I've worked on it. It's okay to have forgotten stuff, but you gotta be able to admit that first instead of blindly charging forwards and assuming you remember how to do it, and do it correctly.

              You've got a nice system though, even today it should run pretty solidly - must've cost quite a bit when you put it together!

                @HighAndDry: lol i understand bro, i haven't built a system in years and needed a refresher.. seems tho i used cpu fan and cpu cooler interchangeably and i guess they didn't like that xD. I will admit my software understanding is lacking.

                nope it only cost me 800-900. i remember getting a few good prices and definitely staying under 1k. Thanks tho.

                  @ayad: Haha fair enough. Yeah I think I'd sound a lot dumber than I actually am if I was getting back into it. Feel free to ignore my other comments - you seem to have it under control.

    I have the same CPU and GPU. However, my CPU is running at 32 degrees. No Aircon, just the biggest Noctua Air Cooler.

      Not surprised, Noctua are one of the best, though ugliest, in the industry. Good choice.

        My case sits below a desk with no window panel on the case door.

        I have a corsair 760t.

        Looks are not something you should care about considering that travesty of a PC you have. lol

          i got it in 2014 lol does it really look that bad xD
