UPDATE: 4 HS's in 3 sizes are needed for RPi 4B:
For all sizes, PLUS other coolers, search
AliExpress &/or eBay f "raspberry pi 4b heat sink"
(Some kits incl 3 of 4 HS's that others provide)

---

We just dug out a starter-kit - with more
than an RPi 4B card in the box; there are
4 Heat-Sinks, each w/ a white [3M brand?]
double-sided tape, presumably able to
transfer heat away fr corresponding chips

There are 3 different sizes, to my eyes:

2 smallest: 8.8 x 8.8 x 5mm (some supply 9 x 9 x 5mm)

Next size up: 14 x 10 x 5mm

Largest size: 14 x 14 x 5mm

When it's Hot in AU, Heat can Kill your RPi
so make sure you add Heat-Sinks [& fan(s)]!

Heat Sinks are 1 Preventative Step Forward

About to buy Amazon's Lot of 10 for $7.93
(photo shows 9, but text says "10 pcs"):

• https://www.amazon.com.au/8-8x8-8x5mm-Aluminum-Heatsink-Rasp…

we thought we'd get a quote fr AliExpress

We leave doing the OzB-req'd Due Diligence
on AliExpress vendors as an exercise for the
Reader, but, in this case, it's easy enough
to find any number of Heat-Sink vendors:

• Search eg: "8.8x8.8x5mm" :fr Amazon offer

(or "50Pcs/lot 8.8x8.8x5mm" for the offer)

How much can a tiny chunk of Aluminum Cost?

Here's a price anyone can afford, even for
entrepreneurial reSale to others sans Club

PS IF you're a Big (or even New) RPi user,
tell us what you've managed to do w/ RPi's :~)

A Next Step towards keeping your RPi Alive
is the Heat-Transfer "goo" you squeeze out
and/or "paint" between your RPi's bigger
chips & the flat bottom of your Heat-Sinks

Amazon has a range, but I need more info
Before I Buy one of the best offers they
have of the stuff:

Q: Are all silicon heat transfer goo's
equally suitable for RPi applications?

Eg, here's "30g" for $5.13 ("Not eligible
for Prime" but it ships for Free…?)

Apparently, a Lot of 5 all-plastic syringes
full of the stuff; but elsewhere in listing
we see "automotive; BrainTrust like 'expoxy

So, not wanting our Heat-Sinks to eg, slide
off our important little RPi "big-chips" we
want to know how this kind of "goo" works &
what the variations are…

Any1 know Silicon Thermal-Transfer "Goos"..?

Thanks!

PS So, where are the good Fan or better:
Cases with Fan(s) Deals? Do fans last long?

      I think Draupnir maybe pointing out the title in which you may have entered it manually.

      Since it does not have adhesive. What kind of glue do you use?

  Lol there are better thermal compound than silicon, and for the tiny amount you will use it will be not much cost, a pc cpu uses a pea sized drop.

  As for sticking on not to sure, it all gets stuck over time 😂

    If we or some1 in the Open [ H/W ] Comm'y
    creates a popular design, we may build up
    lotsa RPi-based kits or assembled systems

    Eg, there's a SDR app'n of RPi, but dunno
    how are they are along with it.

    So we're looking for larger than hobbyist
    qty's in our initial purchase; if nothing
    else, unused portions can go to a school,
    for RPi or simpler "Intro to Electronics"
    labs. It won't be wasted.

      Sounds good :)

  You will want some thermal transfer double sided tape to use with this, or a permanent thermal epoxy.

  Too small for PI4. That size is for Pi1,2

  • 

    IVI on 17/10/2019 - 10:44

    So, what's the PI4 size, already…?

    Better let Amazon know… eg, here:

      I am using this one but bought from ebay
      https://www.amazon.com.au/Raspberry-Generation-Accessories-E…

      Have Run "stress" for 15 min to test it. Highest temperature in core was 71'c . And 40'c when it's idle

        IVI on 17/10/2019 - 11:48

        Thanks for that.

        If you're not in a warm place
        repeat your test this Summer ;~)

  Looks a decent size since core-electronics sell 3pc Heatsink Kit 2 x Small 9mm×9m×5m. And 1 × Large 15mm × 15mm × 5mm
