My E8400 is reporting 51 degrees Celsius and 31 degrees Celsius for Cores 1 and 2 respectively in speed fan (core 0 and core 1 in speed fan interface). My HIS4850 is reporting 78 degrees Celsius in Catalyst.
I am using the stock intel fan with MX2 thermal paste. This is under no load, these temperatures.
What's going on here is GPUs are now larger than CPUs and put out more heat while their coolers are typically inadequate, especially the new reference 4850 GPU cooler and its absurdly low fan speed. Do some Google searching and learn how to turn up your fan speed and better yet, buy a decent air cooler.
Intel also seems to be putting more effort into power management so parts of their CPUs turn off or go into low power modes at idle which really helps keep the temps down, even with only the OEM cooler. GPU manufacturers need to do the same.
Note that today the processor is running at all temperature sensors right in the mid forties.
And about that GPU: right now the case has only one fan, an exhaust unit at the back right behind the processor fan (its a Gigabyte Case). I can add another fan up front and it would blow back over the hard drive and GPU. good idea or waste of time?
