Simple Spec me Cooling post

Just did a half hour stress test with the cooler to check the performance and I'm quite happy with the results.

During load

After Load

Temps across cores settling down now to

32 36 28 28

The second sensor appears to be stuck so giving a false reading :(
 
also it appears you have speedstep on or something similar which is throttling your cpu i think. look in first pic it says clock speed is 2.6ghz and idle clock speed in second pic is just under 2ghz.
 
Never noticed that before.

I think its cos I've got the Gigabyte GEST software running and that does have the cpu throttling on it along with a couple of other features. Normally I just switch it on and leave it running.

EDIT :

I'll try prime 95 again but with the GEST disabled so I'll see what change that makes to my temps etc.

I would check your bios and disable any automatic throttling things like that. It probably wont affect your temps much, its just not going to be very good if your OCing and your bios is then reducing the clock speed behind your back!
 
Ok I've had a wee look around on my pc and found the GEST in windows hasn't had its cpu throttling enabled so I popped into the BIOS for a look.....

Advanced BIOS

Cpu Enhanced Halt (C1E) - cpu will enter c1 state and reduce core clock to system bus ratio and VID

Cpu Thermal Monitor 2 (TM2) - when cpu die temperature reach threshold, both core clock ration and voltage will be reduced.

Cpu EIST function - EIST driver manages clock and VID to best serve the thermal, performance and power requirements.

PC Health

Cpu smart fan control - Cpu fan is always running at highest speed.

Cpu smart fan mode - auto

Also the BIOS is reading the Cpu temp as 26 with the system at 30 degrees C.

I'm assuming that I have to disable all those parts I listed under the Advanced BIOS but the fan control stuff can remain as it is under the PC Health section?

Checked also in the BIOS as the CPU clock speed is only 2.66 rather than the full 2.83 as the chip is supposed to be.

All advice welcome as I don't have a scoobies since this was my first ever pc build :D
 
If you're overclocking and are still trying to find a max, it's best to turn SpeedStep and C1E off as they can b0rk things, but once you've found a stable clock, leaving them on is fine on a modern motherboard.

I think you've got the fan on the wrong way round on the heatsink. That's going to be sucking air off of the heatsink rather than blowing into it. Looking at the manual on the noctua website, the fan needs to be the other way around. Should get the temps a little lower :)
 
My temperatures are better with a smaller cooler. (Arctic Pro 7) and an E8400. Has never gone past 41 degrees full load 3 hours of Prime95. Possibly because yours is a Quad though. Also one of my cores sensors' is stuck at 38 degrees. Other one idles at 30.

At the moment I'm just testing my new cooler. Overclocking will be the next step but I've got to read up on it as I dont have a clue where to start. As mentioned by Fro5tie my cpu is being throttled just now to around 2Ghz - 2.66 during load so I'm wanting to release that to take an accurate measure of temps during load at 2.83 which my processor is supposed to do 'out of the box'

Well i did say i had a couple of minor problems during the cooler exchange :p
Time to take the fan off and put it the right way up now lol.....could have sworn most companies prefer their logo to show rather than up against a cooler

Dropped down a couple of degrees across the board so thanks for spotting that Jon :D

No problem. Looking at the screenshot, is the multiplier set to x8? If you want to get it running at stock speeds it needs to be x8.5. Simplest way to check would be to download CPU-Z and then putting the CPU under load and seeing what the multiplier changes to. If the BIOS on your Gigabyte board is similar to on my Gigabyte P35, there should be a setting called Fine CPU Clock Ratio under MB Intelligent Tweaker. You would need to put that to 0.5 to give x8.5. That would then give you 333x8.5=2830mhz or 2.83GHz which is the stock speed for a Q9550.
