It would be nice if people could mention AMBIENT temperature along with their CPU temps.
Something I've noticed about this setup is when sustained CPU load on all 4 cores goes to about 75-80% the processor "downshifts" to Vcore of 1.10v ( from 1.30v) and MHZ of 1250; is this the action of Cool n Quiet or is it something else?
With an ambient temp of about 81°F. (27°C.) I have AMD Overdrive reporting on light load 41°C. and PC-Probe II says 44°C.
To be fair I'm using an old Supermicro full-tower case with the side door open for now until I can do some metalwork on the top cover to add a fan or 2.
Now I'm running a down-and-dirty stress test of a virus scan, WinZip and ALzip making 2 very large files.
PC Probe II says 49-50°C. while AMD OD bounces around between 43-51°C.
System details:
ASUS M3A78-EMH HDMI motherboard
AMD Phenom 9850 Black Edition 2.5 GHz (not currently overclocked)
4 GB (4 x 1 GB) Crucial DDR 800 MHz memory
Seagate X15 (15000 rpm) 18 GB hard drive (system disk)
WD 3200JB 320 GB IDE drive
ATI integrated video
RealTek integrated Ethernet and audio
PC Power & Cooling 500 W PSU
Windows XP Professional SP3 (32-bit)
Supermicro full-tower case (vintage ca. 2000)
I realize that I don't have the same rigs as you guys here but I run 24/7 at 3.939Ghz and under load my temps are lower than most of your idle temps... We need to get all of your temp down so prolong the life of your CPU's..
Ok buddy.. Here are my idle temps on my rig with ambient temp as well.... specs are in my sig..
PC Probe..
Ambient temp..
Thats 60 degree Fahrenheit = 15.5555556 degree Celsius ambient air temp..
Overdrive..
Well I figured part of the problem. I'm a retard. I put the ZALMAN on backwards so it was blowing the hot air away from my exit fan. My CPU is running at 43 to 45 C idle, and is at about 50 C under load. I do think I need some more air flow however. I'm thinking of moding the side of my case to fit in a huge 220 mm fan.
HAHA.. That will do it..
GO for it on the Case Mod!!! And when your done lets see some pics.. Check
These out..
Zalman is not a great company for CPU cooling IMO.
As for Zalman not making good CPU coolers I have heard mixed reviews on them.. But I got mine for free and have yet to see someone with a compairable rig running as cool as mine.. But everything performs differently for different people and CPU's and MB's, ect....
I use the stock cooler and mine idles at 50c, under load it goes up to 57c. as it causes no problems I have not bothered with an after market cooler.
Those are some really high temp and WILL cause probs over time.. I would really look into some better cooling If you want that CPU to last you...
Sorry for the very long reply.. wanted to get it all out in one shot
Aslo some of you may want to check
this link out.. I see a lot of you are using artic 5 TIM ( I personally use
OCZ Freeze) and this is a good guide on how to properly install it.. Keep in mind tat Artic 5 has a 200 Hr break in period.. good luck to all!!!
