vrm temps, r9 290x - Page 4

post #31 of 39
I wasted no time replacing my stock cooling (for loudly obvious reasons, pun intended) on my 290x to the ARCTIC Accelero Xtreme III. And honestly, I've never considered my VRM temps. Although my GPU never exceeds 70 degrees (GPU @1100mhz / MEM @1400mhz), now I'm concerned about the VRM temps. Sure, I followed the instructions for the ARCTIC cooler and glued the included heatsinks on the memory and VRMs but never gave it much thought afterward as I'm not having any crashes and my fans are much quieter than the stock cooler was on "quiet."

Anyway, I ran my test to check my VRM temps. I used the Heaven Benchmark and let it run for 90 minutes with the Extreme preset. Results below:

Ambient room temp: 24

VRM Temperature 1 (the one reporting the highest) = Max: 92, Avg: 79, Current: 81.

GPU Temp = Max: 69, Avg: 59.9, Current 68.

Fan speed = Highest: 90%, Avg: 57%, Current: 89%.

Observations: After about 8 minutes, the VRM temp maxed out at 92 but as the bench ran on, of course the speeds of the aftermarket cooler increased maxing out at 90% duty cycle. Obviously, the higher fan speeds lowered the VRM temps as time went on. Also, 90% fan speed is the highest I've ever seen these fans hit! Nevertheless, still quieter than the stock cooler on "quiet" (No exaggeration)!

***Note, this test was with a benchmark in the Extreme setting. Great for burn-in, I guess but not realistic for today's gaming. I've never seen my fan speed hit 90% before. Never! The highest I've seen was 65% with Assassins Creed Black Flag (about an hour of gaming). I plan on testing BF4 for 90 minutes after running some errands this morning and will post those VRM results later today.

**Update with my 90 minute BF4 gaming test.
VRM = Max: 85
Fan = Max: 44
GPU = Max: 69




Note below that I have set the Max GPU temp to 70 degrees and Max fan speed to 100% (this is my normal setup). I felt this necessary since the fans would barely spin higher than 30% during normal gaming/testing (a testament to this cooler's efficiency). My concern was that even though the GPU was being properly cooled, only the GPU had DIRECT contact with the heatsink. The memory modules and VRMs, however do not have direct contact and thus required good airflow over their heatsinks that flows through the main heatsink. So setting the Max GPU to 70 degrees forces the fans to spin up much quicker as things heat up thus delivering cooling to the memory VRMs faster and more efficiently.

just use the VRM1 plate from the stock cooler, you will get 15-20 lower temps...

Too late, the heatsinks are attached with the thermal glue.

DO you mean literally cut off the back side of the stock plate from the reference design and hard install it on that...what 1/4th?...of the card?

I'm using the Gelid Icy Vision Rev 2 and the heatsink they provide looks like it'd cool better than that. But with temps at as high as 98C I'm willing to try anything. I'm about to give up and just fully water cool the damn thing.

There's got to be a way to carefully remove them even though they are glued on. Gotta be some chemical that can do it without melting the RAM modules. Has anyone tried to remove them?

Edit: And no, I did not glue mine on. I'm just thinking out loud here.

I imagine if you were to run the card hard, power off and immediately work the sinks off while still hot then maybe.

Run a scrypt coin miner. Overvolt a wee-bit. Prevent active airflow over the memory heatsinks.

Then rush to pull em off. Could probably just close the miner or lower intensity and continue to run computer while pulling them off, in an attempt to keep them hot without burning the ones that had the heatsink pulled already.

Some people have cut that section off, I prefer my method HERE

I've had 5 of these 290/x's & done 2 builds with 290x's. Out of 7 cards only 2 had VRM temp readings. Some have them, some just don't thumb.gif My current one does in HWinfo64 but not GPUz


Custom aircooled/Vrm sinked.
