I recently purchased a His 6870 iceQx and I noticed mine is running hotter that the others.
Mine runs at 52 C while idle and others has posted on websites that normal should be 32 C.
Mine under stress runs normally, 65 C which is OK. Room tempearture is 25C.
Is there something I should do?
I contacted hisdigital.com, I guess a non technical person took my case and suggested to RMA and get replacement, but that is not an option since I am currently in another country from where I bought it.
One day when I cleaned my Old Computer. Which wasn't clean from a year.
I found that the Gap between the CPU Fan and Processor was filled by Alot of dust and Webs of spider.
I cleaned it and then found this big margin:
Idle Temp: 54
Full load Temp: 65
Idle Temp: 39
Full load Temp: 57
So I'd say that you should clean your GPU with a Blower.
If you cleaned properly and then also nothing decreased then send it to RMA.
