HD6870 Twin Frozr idling over 65C

post #1 of 3
Thread Starter 
Hey!

I just got my build assembled today and everything looked just fine judging by the first glance, but here's one thing that got me a bit worried...

My CPU (2500k) idles at 35C and load temps are around 55 - 60C. Fine for me, considering Mugen 3 isn't exactly the most effective cooler around (although more than adequate for my purposes!). Ambient's near 30C too, so that may be one factor contributing too.

The shock was yet to come... My HD6870 idles at 65C - 75C degrees. That's with fan set at 30% (via Afterburner). Raising the fan speed, even up to 100%, doesn't help much and will drop temps only to somewhere around 55C.

When idling, (that is, in Windows), my core clock drops from 930Mhz to 300Mhz. It occasionally spikes up to 930Mhz, eg. when watching YouTube. That's normal as far as I know. Then there's the memory clock, which sits faithfully at 1050Mhz, regardless if it's load or idle.

The weird thing is that my load temps aren't that high. Running MSI Kombustor, I only get around 70 - 75C with fan running at 60%. Looks a bit high, but welll within the limits, not the case with the idle temps!

Then there's one more thing that got me alarmed. More I raise the GPU fan speed, more distinctively I do hear a clicking noise that repeats every 5 seconds or so. First I suspected I had a faulty PSU or HDD, but I think I'm pretty sure it's the GPU, because it's almost inaudible when the fan is spinning at idle speeds (30%), but easily overcomes the fan noise at over 60%.

What could be wrong? Did I get a faulty one or ...? What would be the correct way to resolve this situation, would it help to contact MSI directly?

Could be a sensor issue.

What's your ambient air temps?

Feel the air around the 6870, if it's not hot, it's a faulty sensor.

Thanks for taking your time to reply.

I got the problem sorted: I found out that due to my crappy cable management (you can't get it right first time, eh?!), one SATA power cable was in fact blocking the right fan on my Twin Frozr from moving. I hope no permanent damage was done, it seems to be functioning all right now

Idle 31C (fan 30%) and at load 62C (fan 60%)!
