I just ran Prime95 for 7 hour and left my CPU and case fans on FULL. I looked at the temperatures and fan speeds just before I stopped the torture test. This is the Stock AMD HSF and Stock HAF 912 Case Fans (2) on Full.
I've already found I have a problem in the fan controller sensor, when take the fans off Full and I set it to manual mode, it reads only one fan accurately and the other shows similar reading for 9 out of 10 every 10 seconds- then jumps to double the speed it was reading for 1 second or reads N/A in the Bios/Cmos.
Prime95@7hours RESULTS CPU: 42-43 C (Core 1: 38 C & Core 2: 38 C) MB: 31 C CPU FAN: 3750 Chassis fan front: 1147-1200 RPM Chassis fan rear: 1159-1180 RPM
What are reasonable temperatures? What are realistic fans speeds? Anything else odd on the reading?
Here's a screenshot:
Idol RESULTS CPU: 31 C (Core 1: 21 C & Core 2: 21 C) MB: 31 C
Are these accurate or inaccurate too... I need a baseline to figure out whether I have a fan controller issue only or fan controller and temp sensor issue too - The first I suppose I can live with - the second I probably would need to return the mobo to newegg (I've had it 2 weeks)...
Hmm... I could do a quick disable of two of my 965's cores and see what temp results it gives me for a comparison, but I doubt even then it would be anywhere around there. Our setups are basically the same, only my case is the CM 690 II Advanced with a Core Contact Freezer... I know how far that drops my temps, though, so it shouldn't be a problem.
Huh. That's interesting. I'll look into this and get back to you in the near future.
I have built 4 AMD machines in the last year ish 1 with a Phenom x2 and 3 with Athlon x3s and none report remotely accurate core temps, ie the PC i am typing this on reports 2 cores at 11C 1 at 12C when the room temp is 19C. I recommend you go by the CPU temp and ignore the cores totally. If you do that your temps all look fine and accurate. My Athlon x3 is currently idle ish at 26C (7C above room temp) but I an using a hyper 212+ on a system thats not overclocked (I had one spare if you are wondering why).
