Raspberry Pi Copper Heatsink with Sticky Thermal Pad for Raspberry Pi 4 / Pi 3 / Pi 2

I'm using this on the GPU of a PI, which is installed in a FLIRC case. The FLIRC case takes care of the CPU, this heatsink takes care of the GPU. I have monitored the temperatures and both CPU and GPU stay withing the 40's. Without anything, a Pi that plays a video can see temperatures in the 70's and that just cannot be good for electronic components. I highly recommend this particular product for the Pi.

Temperature under load still goes above 80c within a couple of minutes. Would instead recommend a case fan. Temperature under load still goes above 80c within a couple of minutes. Would instead recommend a case fan.

This heatsink is slightly smaller that the Raspberry Pi 4 CPU chip.
It measures approx: 13mm x 12mm x 4mm
I've not tested the RPi4 temps without it so I can't say how much difference it makes. This heatsink is slightly smaller that the Raspberry Pi 4 CPU chip.

Fits the Pi 4 B okay however it’s slightly smaller than the processor. A better option is to buy the fan and heatsink from PB Tech. Only a few dollars for both and the heatsink is larger. This still does a good job though. Fits the Pi 4 B okay however it’s slightly smaller than the processor. A better option is to buy the fan and heatsink from PB Tech.

I buy this sort of thing kind of in bulk as I will use one here or there Looking at this one it should perform better than some other designs, as the surface area is maximised with the grid layout. Though anything worked too hard can throttle as the heat sink thermaily loads up. Your mileage may vary batteries not included and you may just need a fan with a PI 4B...

the item was recieved in fast time but was way over packed. item is about 25mm x 25mm x15mm and was in a box 250mm x250mm x 150mm huge box for little item. the item was recieved in fast time but was way over packed. item is about 25mm x 25mm x15mm and was in a box 250mm x250mm x 150mm huge box for little item.

Excellent quality with speedy delivery in level 4 lockdown. Excellent quality with speedy delivery in level 4 lockdown.

Helps to dissipate the heat if you have a large fan blowing all through te board. Without the fan temperature drop is insignificant, less than 5 degrees Helps to dissipate the heat if you have a large fan blowing all through te board.

The heatsink works as it should be. The heatsink works as it should be.

I didn't expect too much from this and I got what I expected. It does drop temperatures a little but it's no substitute for a fan and/or much larger heatsink.

Simple, fits on easily, works. Simple, fits on easily, works.

works very well and easy application to the chip, keeps the Pi4 temp idle around 42C and 61C at 100% while compiling Quake3 works very well and easy application to the chip, keeps the Pi4 temp idle around 42C and 61C at 100% while compiling Quake3
