Need help picking heatsink for R9 290 VRM - Page 7

post #61 of 125
Btw Enzarch, yea I wish I had seen your guide before I raped my cooler =( I forced it off with a flat screwdriver + hammer and the memory area was too bent to use =/
It did'nt cross my mind that the solder whould melt just in the oven tongue.gif But thanks for the guide anyway, will keep it in mind for next card wink.gif

Any more suggestions?

The heatsinks that came with my Arctic Hybrid cooling are "OK" on stock volts while gaming, but really not very useful when I start to mine coins (cgminer) with temps upwards of 100c.

Also could use some advice on thermal tape that is easy to remove should the need to RMA the card arise.

Dont use thermal tape, use Fujipoly thermal pad. But then you need to be sure it is strong enough to hold it. It can hold maybe a gram per cm2 but nothing major. If it wont work for you then I can say from experience 3m 8810 thermal TAPE is the weakest most awful adhesive I have ever used. Its worse than thermal pads not meant for being adhesive in the first place. Its extremely easy to remove though, heh.

I got myself some SEKISUI 5760 Thermal Adhesive Tape Double Sided 8"x1" for my accelero 290 install since I didn't want to mess with mixing epoxy which I had mixed results with and tried to stick together two of the smallest heatsinks that are about 5x5mm and it seemed to hold pretty well when I tried to separate them. Not sure how the adhesiveness changes with temperature but seemed like even half of that when cold should be enough to hold them. Still waiting for my card though, hopefully on 30th it will finally arrive.
I plan to use it on ramsinks and the small vrm section. For the strip I plan to mod some heatsink I have to use the holes and thermal pad.

290x here, with mkii bracket & corsair h90.



I have no VRM heatsinks at the moment, I have a Corsair 540 case, and a 140MM fan sitting on my HD tray blowing air up at the middle of the card. I've noticed VRM2 doesn't seem to differ much at load or idle; VRM1 on the other hand can get pretty toasty. I am considering picking up another fan to mount on my actual HDD to see whether that could provide sufficient cooling for overclocks.

(stock clocks)

max idle (fan controller --> put all fans at minimum, including radiator & noctua fan directed at 290x)
core 35c
vrm1 32c
vrm2 46c

max load
core 51c
vrm1 89c
vrm2 53c

would just like to dedicate a single post to how simple it would be to make a VRM heatsink for VRM1 on the 290 reference PCB, and in the process, make some money for yourself. If there are any artisans out there (or big corporations...NZXT?), package some thermal tape, screws & washers, and make some heatsinks of the correct size, and start selling VRM heatsinks specifically designed for the 290! You will fulfill an obvious gap in the market thats evidenced by 7pg of this thread, providing good VRM1 cooling, in a removable solution, that is sure to last long term (because of the conveniently located crew locations).

yes, I realize some folks have referenced certain options of this sort before, but as far as I can see, there has been no official 100% post on compatibility

I was under the impression that VRM 1 is just to the left of the red bar. The three memory chips to the topleft are VRM 2. Anyone else want to verify?

correct; VRM1 is the core vrms in the long line towards the power connectors

Based on what other have said it depends on the software but the long row is the hotter of the two.

installed accelero on my 290 today and the vrm temps look good so far...better then with stock blower
http://www.overclock.net/t/1458643/black-screen-immediately-under-load-after-installing-accelero-on-290-solved-now

not sure it helps though as all the heatsinks I used were accessory for aftermarket coolers and not sure if can be bought separately
