Any way to reduce CPU temperature?

When i run CPU intense games such as Black and White 2 or F.E.A.R. on my M6N it seems that ASUS Probe reports that the CPU temperature goes above 90 degrees C which is obviously bad. Anyone else having similar issues? If so is there any way to get around it by adding something or perhaps modifying something. I'm a bit pessimistic that there is a solution since it is CPU temp but i thought it wouldn't hurt to ask anyway!

Btw normal idle or websurfing temperature ranges normal around 45 degrees or 50ish depending on use. I dont believe thats a huge issue, but it might be!

 

I have to wonder whether the fan is working properly if the CPU temperature gets that high. What fan speeds does Asus Probe report for different temperature?

The other way to reduce temperature is undervolting. There is much discussion about this in the forum. The first thread is http://forum.notebookreview.com/showthread.php?t=15492 .This has dropped the maximum temperature of my CPU by at least 10C.

Yeah, it sounds like your idle temps are totally normal, but those high load temps are way to high. I've hit 70 after a long session of HL2, but I don't think it's every been higher than that. It does seem like maybe the fan isn't working properly, or something in the BIOS or whatever isn't telling it to come on...

 

have you actually seen the temperature reach this high or it just a sparatic warning. The reason I ask this is sometimes the temperature can be reported falsely because it is an analog device and shares pulse modulation with the other sensors. And without getting into detail, sometimes certain condidions, almost like harmonics, happens that causes the reports to be messed up. I've never had anything reporting high temperatures, mostly it'll report something like -130 deg C, which you know is clearly false.

The best way to check is to download Prime95 and run the torture test on it. Watch the temperature and see if it climbs past 80+ deg C. If it does, you clearly have a cooling problem. Unless you have made some kind of overvolt mod, there's now way it should get that hard unless: 1) heatsink isn't seated correctly or you have too much or too little thermal paste contact between the heatsink and CPU. 2) your fan is seized, malfunctioning, or not connected to the motherboard. 3) There is a malfunction is the sensor and/or reporting software (the former is highly unlikely since the diode is on-die).

 

I have actually seen the temperature hit this high, ASUS probe goes crazy and warns me that i'm doing something bad. I've played HL2 with no problems it's just when i try newer games. I havent actually reseated the CPU or put any thermal paste, other than the addition of a stick of ram the thing is pretty much like the day i got it. The fan does spin at a higher speed, it hits 4000rpm and i think thats the highest it goes. The fan also does seem to spin OK as i can hear it whirling around. I'll try the torture test and see how that runs and report back.

EDIT: Looks like it does go above 80, will crack her open and check to see if anythings loose or whatever. Btw is there supposed to be any thermal paste or anything on the cpu? I dont remember if mine came with any.

 

ewwww, looks like i just may have solved my own problem. Opened up the machine and found a big clump of dust where the airvent is, cleaned it all up and its running alot cooler this time around . Good stuff, thanks for the input everyone.

 

Haha...good to know it was only dust!
Makes me wonder if my M6Ne has any trapped dust...

 

I've had mine since early march 2004, so its been about a year and a half now. If you've had it as long as i have, chances are you probably do .

 

I got mine at the end of September last year... so I'm not quite there YET, but soon enough...

 

i don't read wierd numbers like 715... but auroraS is that still your old 1.6GHz P-M? If so, it doesn't heat up much and the fan should almost never run unless you're playing games. At least that's what I found on my 1.5GHz P-M on my old m3np. I do find now however, at 2.26GHz that the fan will turn on (very lighly, like 1000rpm) every once in a while when i start doing CPU intensive stuff (not games, cuz of course, games heat everything up). So basically, what I'm saying is your fan probably hasn't run much, so it's unlikely to have much dust on it.

 

The P-M 715 is a Dothan running at 1.5 GHz... yeah, the fan barely ever comes on; however, since CHC is compatible with the M6N, I purposely make the fan turn on at 55 degrees... otherwise, fan behaviour is quite sporadic.
