Hi !

I recently bought a Sapphire R9 290X. It performs like crazy and everything is fine...except for one thing.

I´m using Gpu-Z every no and then to check voltages and temps e.t.c anf it reports a very hight temp on the VRMs. There are 2 temps reported...VRM1 and VRM2. During load VRM1 says 95-100 degres C depending on what game/ benchmark I use and VRM2 says around 70 degre C. 

Is this normal ?
If anyone else with R9 290X would be so kind and check there VRM temps and report back...it would be much appreciated. Preferably Saphhire users, but any one with a referense designed card will do.

I can't say definitively, but that sounds fine to me.  VRM temperatures don't tend to be a problem until well about 100C.  Given the cooling algorithm of the card, I'd expect those kind of VRM temperatures.

Sounds about normal to me too. AMD's reference cooler is quite crap, has been for many years, and has a habit of not cooling all parts of the card effectively. Take the HD 5970, for example. Most of the card would be adequately cooled, but one bank of VRMs wasn't and could trigger thermal shutdowns by getting over

mind for card 1 was VRM1 67C and VRM 2 83C GPU-z unfortunatley dosnt keep track of the second card for me.

THNX guys for taking the time to answer.

Yesterday I saw once the temps on VRM1 top out at 105 C after playing Company of Heroes for about an hour or so.

It just doesn´t seeme right.....but maby I should just relax about it.

VRMs are made to withstand the heat much like capacitors. Might want to ask Sapphire just to be sure though, there is always a chance that some idiot in the factory missed a thermal pad, or the heatsink is slightly warped in their location making it not make complete contact.

The stock PowerTune/cooling profile for the R9 products will allow the product to hit a target temperature of 95c.  I prodded at the Product Trainer last week a few times to verify that the product was developed accordingly, and AMD is standing behind the product gaming away at 95c all day long. 

They assured me as such.  I would simply make sure your case is well organized and well designed with an effective case-fan setup.  Beyond that, consider reducing the target temperature down to 90c.  You'll sacrifice a tad bit of performance, but I doubt it would be much.

THNX for the reply...but it´s not the gpu I´m worried about...it`s the VRMs.

Seen as it's made to run at 95 all day, is there any addverse effects to over cooling then?

Like drop in performance/stability?. Was going to water block my 290x

I Have never tried to cool my gfx beyond watercooling...but in theoryit should take damage if you would go subzero. 


In adition I had a little chat with the support att Saphires "Selct Club"...I asked about the temps and attached a screenshot with my VRM temps during load and this the reply I got:

Yes, VRM temp normally over 100c and sometime goes to 120c. Yours just fine. Just make sure system fan working good and monitor the GPU temp. Sorry for your confuse

 Regards

It's designed to not fail at 95C, not to work optimally at that temperature.  It will perform much better with water cooling, since it will never have to reduce clock speed to maintain temperature.  It won't even get near the 95C target temperature on a water cooling loop.

It remains to be seen whether or not overclocking on water will yield any benefits.  I've heard that you can't adjust the voltage in any way, so if the inherent voltage scaling doesn't continue beyond the factory 1GHz clock, you probably won't get much higher without errors.

Great news, the Tomshardware ask us anything . Apperently AMD isn't going to be allowing there partners to make Non Reference coolers for the 290/ 290X any time soon. 

The other news. Is the artic accelero easily will allow the R290/R290X to hit 1100mhz all day long.  No water cooling required. I mean unless you want to that is.

I wasted no time replacing my stock cooling (for loudly obvious reasons) on my 290x to the ARCTIC Accelero Xtreme III. And honestly, I've never considered too much 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 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 barely audible (even after hitting 68% workload). 

Needless to say, the first thing on my agenda when I get home tonight is checking on my VRM temps. I will post what GPU-z reports.

 

Ok so 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)!
