R9 280X idle at 55°C, way too hot?

My XFX Radeon R9 280X has been running at an idle temperature of 55°C on my new pc. I feel that is way too hot.

When I assembled it a month ago, it was around 45°. Back then I was still using the Intel stock cooler, so temperatures should have been higher. In all fairness, the weather in Germany then was noticably cooler, about 20-25°.

Today the ambient temperature is about 30°. I no longer have a stock CPU cooler, but instead a water cooling loop that blows air from the radiator outwards. And yet the GPU is idling at 55. Load temperatures are 75°, today and before.

1) Could it be a problem with the video card? FYI there was an odd mishap when I was installing the water cooling loop: the GPU failed to work after I finished it (could not be detected at all, although the fans were still spinning). I had to reinsert it in another PCI slot and reinstall the drivers for it to work again.

2) Could it be malware? Will hidden programs make use of the GPU? When it is idling, the GPU load is nevertheless at 0% in GPU-Z.

Those temps shouldn't be anything to worry about. When you changed coolers and moved the GPU the air flow of the case changed as well, that and ambient increase could account for the change in temps you are seeing now.
 
Is it overclocked?

Ambient 20 to 30C will add 10C. On idle at 30C ambient I'd expect it to be at 45C max

Big airey case? Case fans spinning over 1000 rpm? GPU fans over 1000 rpm?

Spilling water on it and pcie slot wouldn't help. Did you dry everything out 100% before re-trying?

Not likely Malware.

Nope it's not overclocked. Runs at the factory overclocked 1080MHz. GPU fans spin at 1800rpm at 55°.

Mine being the Corsair Air 540, I would indeed call it a big airy case. Three 120mm front intake fans spin at over 1100rpm, 140mm exhaust at 900. I wouldn't call it a fan problem though, I actually took my table fan and aimed it directly at the card, no decrease in temp.

As you can see from the pic, the card used to be located in the slot above. Now it's mounted closer to the bottom. I can feel substantially hot air above and coming out the sides of the card.

I am quite sure I didn't spill any water. I did, however, sharply bump the card at the corner while I was working on mounting the radiator... Perhaps that caused something to go bad?

I kept an eye on GPU-Z while playing a game, and the voltage seems stable at 1.2V. However, the idle VDDC Current is at 50A, and goes up to 180A under load (peaks at 250A). I'm assuming this isn't normal...?

Unfortunately I don't have another PC or graphics card at my disposal to test on :/
 
I think that's OK 1.2 x 50 = 60W.

1.2 x 180 = 216W - too big!

1..2 x 250 = 300W NO WAY!

I think it's got a short init. Maybe its still partly wet. DRY IT OUT thoroughly - 2 days in front of a blow dryer or similar. Same with your motherboard.

If you're still getting the same readings then its time to junk the card and/or the mobo. You'd need to test the card in another pc to see if the card is faulty. And test a good card in your pc to see if the mobo is faulty.

The funny thing is, the card seems to be working fine apart from the insane current draw and temperature... I'm not experiencing any frame loss when gaming.

Is there a way of determining if the problem lies with the card, or the motherboard?

Also youshould move the gpu to the top slot. Why did you use the bottom one? And did the water really get over the gpu?

The OP has stated that he moved PCI slots because the top one stopped functioning after he had his hot swap issue and he has also stated that he did not get water on the card. I am still under the impression that his temperatures, are 1. not to be concerned with as they are fine for a GPU, and 2. may be caused by air flow in the case changing due to component being moved and a water block not circulating air like a heatsink/fan would.

Actually the GPU is still being cooled by fan, I never changed it except by swapping PCIe slots, because the first slot is (still) not working. The temperature is not so worrisome now as the VDDC current draw (although they're probably related). I mean.. 50A at idle and 200A under load?! Is it a miracle it hasn't burned itself out yet? I dried the components thoroughly, though I am sure nothing was wet to begin with.

If it is because the heatsink somehow got displaced, that should not affect the current right? I'm forced to believe it's either

a) a short in the GPU...

b) or the more likely faulty motherboard... because one PCIe slot stopped working.

The only way I can think of now is buying a new mobo and card for testing, then returning the one that is not needed :/

Sorry for high-jacking the post but could anyone jot down the GPU temp at idle and at load stage ? for asus r9 280x so that we can get a better idea. Is there any way to check is the GPU is not damaged or anything of that sort ?

I have a MSI R9 280X and a custom fan profile and mine stays around 31 degrees at idle and reaches 70 degrees maximum at full load.
