I have a Phenom x4 9650 CPU and I want to measure the temperatures on load before and after my new CPU cooler. (I am on stock)

I am running Prime95 on 'In-place large FFT' and was only getting about 46oC after 10 mins. So opened another instance of Prime with the same settings which brought it up to 47oC after another 10mins.

I must be doing it wrong, because with a stock cooler on full load, I would expect a lot more! I am monitoring temps with SpeedFan, I am looking at the temperature 'CORE', but I have noticed that 'TEMP 3' goes up to about 55oC when I run the test, is that the chipset?

Also, what do you think of this nice cheap CPU cooler I am getting :http://www.spirecoolers.com/main/product_detail.asp?ProdID=939 may do a little overclocking, should be better than stock! I got some Arctic Silver Ceramique TIM to go with it.

Posted in CPU section but thought it would be more appropriate here.
 
Just trying small FFT now, thanks. Whatever temp3 is it is really burning up, getting a bit worried at 57C!
 
Its been going for over an hour now and the highest it got is 50oC! Running 2 instances of it as well and am using my computer fine! Usage is 100% on all cores but I can do stuff and watch HD video with no lag.

I will give LinX a go, but it looks slightly complicated and CPUs aren't my forte!
 
OK, please reply to this, I dont know whats going on!

After running two instances of Prime95 on small FFT both CoreTemp and SpeedFan reported a high of 50 degrees but the temperature was back at a solid 47 for the next 10mins I physically watched it.

I then stopped Prime and launched up LinX. I dont really know my way round the software but it seems my memory will only let me go up to 13000 problem size. After running for half an hour, temps dropped to low 40's/high 30's. That obviously wasn't going to work so I relaunched both Prime instances.

Temperatures stayed at around 46 for ages. So as a last resort I ran the Heaven Benchmark, FPS stayed averaged at 46FPS and the temps didnt pass 48. And as you can see in my sig my PC certainly isn't hench!

I must be doing something fundamentally wrong, I am using a STOCK fan and not hitting 50 when running all those things? Am I measuring the wrong temperatures? I know I need to let them run for longer, but I'm looking for a method that works so I can leave it to work out the temperatures. The CPU cores are all at 100% though.

The only answer seems to be that AMD accidentally supplied me some kind of liquid nitrogen cooler disguised as a normal AMD one!... or I'm doing it wrong
 
Download IntelBurnTest v2.3/2.4 and CoreTemp 0.99.5

Run IBT 20 loops of maximum RAM stress testing and watch your temps in CoreTemp. (before you run it, close down any background applications so the IBT will make a use of the most RAM; then you can run whatever you want in the meantime). If you pass it succesfully, run 8hrs of blend torture test in prime95 with CoreTemp in the background. Report back ;)
 
I thought IBT only worked on Intel chips. Something to do with the binaries being coded not to work with AMD.

Coretemp is a better program to use than speedfan for temps though. Maybe you're lucky and have a cool running chip.
 
I'm not seeing the problem.

You're on stock cooling but you don't appear to have overclocked your CPU.

The stock CPU cooler is perfectly capable of of looking after the chip if its not overclocked which could bump up heat output beyond what stock cooling is meant for.
 
Worked it out! I was measuring the core temps rather than the CPU temps. I used CPUIDs HWMonitor and found it was about 55*C idle!!

The reason I am doing this is that I want to compare the idle and load temps between the stock cooler and Spire's CoolGate 10 cooler that I'm getting. I would appreciate it if you took a look at the cooler (link in OP) and told me what you think it will be like compared to stock and other coolers.

I don't plan on much OCing, maybe 1 or 200MHz but am looking at slightly lower temps and quieting it down a bit!
