R9 290X + Gelid Icy Vision using modified AMD metal plate for better VRM cooling
Last weekend I had a bit of fun trying to replace my stock R9 290X coolers with Gelid Icy Vision!
Long story short I did one of my R9 290 couple of weeks ago, but went with Gelid provided RAM sinks and VRM radiators. The result was good but not great as VRM1 temps went up compared to stock card quite a bit. When mining my R9 290 VRM1 could go as high as 88C-91C in my crowded HTPC case compared to around 68C - 70C with stock cooler running custom fan profile. Obviously GPU temperatures were much better using Icy Vision and noise came down massively :cool:
To modify my main PC CF 290X setup I've decided to try and reuse original AMD VRM/Memory plate. I mean, how hard can it be?
Lets start with bare card first:

When taking plate off, be careful not to damage thermal pads as they can be reused!

Next step should be to transfer all thermal pads back to card (something I didn't do first time around hence pads are a bit dirty, my 2nd card in the background was done much cleaner)

Now we should have plate with soldered radiator ready for separation. Take the fan out first and then, either using soldering torch or oven, heat up the plate and radiator to around 230C for it to separate.
End result should look like this:

Next step is to cut bigger hole in the plate to accommodate mounting plate from Gelid (I did it using angle grinder and metal file):

For the new radiator to fit this bit has to be half the original thickness:

Nearly there! Notice that bottom memory chip is only half covered by block, but that's fine.

Nice fit after putting screws back!

VRM1 temperatures down to 56C - 60C (gaming, benchmarking)! Card is now cool and much quieter even though Gelid fans are not PWM (this can be fixed with any fan controller)!
Now for CF setup I strongly suggest 4 slot spacing between cards as 3 slots is not enough for good airflow to the top card. Once both cards have enough breathing space temperatures are amazing for the price!
I only paid around 30.00 UK pounds for each Icy Vision and for that price you can't get cooler on R9 290X!
To finish off, for those wondering what are the temps under full Litecoin mining load:
GPU - 61C
VRM1 - 63C
VRM2 - 57C
Reading taken from bottom (cooler) card after 24h of 100% load. These readings should be representative of single GPU configuration ;)
The whole process took me 5h to do 2 cards, but the 2nd card was done in well under 2h as I already knew what to do.
I'm happy with the result and regard that 5h as well spent! My PC while mining can't be heard in the next room any more! Wife is pleased and I can sleep well, knowing my cards are at more reasonable temperatures for 24/7 :up:
