Radeon 5850 so so hot

[seedler]

Specs:

Biostar T5 XE
i5-750 @ 3.6ghz
4 GB XM3 DDR3 1600
HIS 5850 @ stock
Seagate Baraccuda 750GB

Now, I bought a Cooler Master H212 plus, and the i5 runs at 24C idle and 36C load, I'm loving it. Best $30 I've ever spent.

I wish the same could be said for the Radeon, but it running strangely hot:

From EVEREST:
GPU Diode (DispIO) 50C
GPU Diode (MemIO) 54C
GPU Diode (Shader) 50C
GPU VRM 45C

These are IDLE temperatures X_X

Under load, these temps all jump to the mid. and high 70s.

I have the fan set to automatic adjust fan speed, because if I turn it up too high (past 70%) it sounds like a jet engine.

From the reviews I've read, the 5850 should NOT be running this hot. Clearly, this is the reason why games crash after 10-20 min. with any sort of overclocking.

Any ideas as to why it's running so hot?

P.S. Ambient temperature is 26C, case airflow is good with 1X80mm side exhaust fan, 1X120mm front intake fan, and 1X120mm back exhaust fan.

those temps aren't that bad. idle temps are a little high, but load temps are what really matters.

Idle: 42 Load: 80 http://www.anandtech.com/video/showdoc.aspx?i=3650&p=13
Idle: 41 Load: 82 http://www.hardocp.com/article/2009/09/30/amds_ati_radeon_hd_5850_video_card_review/7

I think you just have a poor OCing 5850.

Ahh I see, so out of those Everest temps, GPU Diode (DispIO), (MemIO), (Shader)
GPU VRM, which one is the "GPU Temp" that reviews refer to?

 

[Udgnim]

for GPU temp, the linked review sites probably use the temp displayed in CCC

I'm not familiar with Everest, but using GPUz with my 4870, the GPU temp stays within 1C of GPU (DISPIO). so if you really like to use Everest, I'd guess the closest thing to GPU temp in Everest is GPU Diode (DispIO).

my 5850 idles at 30c with fan at 25%

most games only push it into high 50's and low 60s with fan at 30-35% with 850/1200 clocks.
