New system is getting very HOT.. NEED HELP!!!

Okay I just put together my new system as you can see the specs below in my signature... I am getting some really really HOT CPU temps though.. I am running motherboard monitor and running Prime95 right now and my CPU temps are going between 60-65 C... ouch!!! When there really isn't any load on the processor it seems to be around 39-41 C but as soon as I start putting load on the processor the heat jumps up. I am using the stock Intel heatsink and Fan, and I removed the black tape on the bottom on the heat sink, and I cleaned it with rubbing alcohol. I then put on a nice coat of Silver compound Thermal Grease made by Antec, and I then put a very thin coat on the CPU as well. I put the heatsink and fan on with no problems, and I am running my system at the stock 2.8ghz speeds.. no overclocking.. YET.. so does anybody know why the heck I can't get COOL temps? This is really concerning me and my damn alarms keeps going off because my CPU temps are getting to high. What I did was took my log files from MBM 5 right now and put them up on my website. These log files are from when Prime95 is running and at the same time while I am typing this message. Check them out, I have all my Fan speeds on there, all my voltages, and all my temps. Tell me if you see anything strange on any of the indicators.. I don't know why it is running so hot.. I have case fans and my room is very cool around 65 degrees farenheight because of my AC unit in the wall. I don't know what is going on here but I don't like it.
Here are the links to the log files:
Interval Log: http://cybassist.com/jkevin/mbm_log/MBM 5 Interval Log.html

High Low Log: http://cybassist.com/jkevin/mbm_log/MBM 5 High Low Log.html

Oh yeah.. and one other thing.. when running MBM 5 with a Hyperthreading processor, MBM shows 2 CPU usage indicators.. I guess because it's reading 2 virtual processors.. but when running Prime95.. neither of the CPU usage indicators get to 100%.. should I be taking BOTH indicators and adding them together? Or should each indicator get to 100% on it's own? I know when I run this on my p3 system it stays pinned at 100% but that isn't hyperthreading either. Just let me know.. thanks

I would suspect that mbm 5 isn't calibrated right or simply doesn't give accurate readings with your board. Next time you hit 65c, hit reset and check the temp reading in the bios hardware monitor. My p4 tops out at 59 c, but my room temps are about 85 f.

No I think it's calibrated right.. when I installed it even had an option to choose my board.. the Abit IS7. When I looked in the Bios it was a bit cooler but still up around 55C.. so I think I am running very hot.. don't know why.

When you put Thermal Paste on your heatsink.. this is how I did it. I coated the entire base of the stock p4 heatsink and I used a business card to smooth it out evenly on the entire heatsink. I then took a little more thermal paste and put it directly on the CPU chip. Again I used the business card to smooth it out. Is this alright? Or is that too much paste and that could be causing my high heat?

heya mixerman;

most people are running at about 108-F with the p4c, you just didnt get the heatsink mated properly, try again, keep trying untill you get it right.

what do you mean I didn't get it positioned right... really there is nothing to mess up.. you just put the thermal paste on there and then put the heatsink down into the square slot... then just push the locking latches into place to secure the fan and heatsink on the ship. It really is fool-proof I think... the p3's were definately a bit more of a pain in the but to mount.. but the p4's seem like you virtually CAN'T mess it up being that it is a square that you just drop the heatsink into. Is it possible that some p4 chips run hotter than others? Maybe I just have a hot chip? Could the Antec Thermal paste I use be the problem? Or is my case temp too high.. around 105 degrees F ?

also when you say most people's p4c's run at 41C.. is that running at that temp when the computer is basically idle under NO LOAD..? Because under no load, my p4 2.8c runs at about 41C, but when I put on like Prime95 torture test, it goes right up to 55-62C

So what is the normal temps for the p4 2.8c Under load.. and NOT under load?

Switch thermal pastes to Silver. That dropped my AMD CPU temps quite a bit.

I dont' know if that is as good as this Artic Silver 3 stuff that everybody talks about.. but it is silver..

That's good stuff. It works just fine. Dunno what could be causing the high temps. Perhaps air flow through the case is bad enough that it is causing CPU temps to go up? Dunno. I'd have to say that I'd check the fan CPU mate and watch that closely. Sometimes, some fans are gay and don't want to mate the way they are intended to mate (no pun intended on the gay part, I only noticed it when I previewed :p ). So keep an eye on that. Or if you feel froggy, pick up a new Proc Fan and make sure you get a kick arse one. Check Thermaltake or Zalman for some cool and good fans.

Anybody know what the specs are for the stock p4 2.8c heatsink and fan? Such as what RPM should the fan on the heatsink spin, etc.??

Also, one of the fans in my computer is called an NB fan.. what the heck is that. I know that the System fan is the Antec PSU fan, and that the CPU fan is obviously the fan on the heatsink.. but I dont' know what the heck the NB fan is..

Also, my fans have those big ugly 4-pin molex connectors. Do these new case fans get powered by that little 3 pin connector that you plug into your motherboard only?

heya mixerman;

it may just be that you dont have enough case cooling, it may be building up heat because the air is trapped with no where to go, do you have an exhaust fan blowing air out of your case? If not that is likely the problem, adding an exhaust fan will do the trick.

yeah I have 2 x 80mm exhaust fans.. but I was considering buying a new case anyhow.. what do you think about the Thermaltake Xaser V2000A.. do you think that's one of the best cases out there today? What would you recommend I go with?
And I am wondering if it is better to try and find a case without fans in it so I can order different fans to put in it.. such as those Panaflow fans that Crashman recommended.. I read up on them and they seem better than the Thermaltake fans that come in that case.. what do you think..?

<A HREF="http://forum.abit-usa.com/showthread.php?s=&threadid=11..." target="_new">read the Abit forum</A> and you will see that the Abit IC7/IS7 series (and maybe other Abit boards too?) run a little warmer.

There's huge discussions on who is right ... Why Abit is screwing their customers and then why the customers are just over-reacting.

Anyway, run over there and read and it should make you feel a little more comfortable.

Just FYI - I have an IC7-G (specs below) and I run around 50C idle +/- some ... then under load, I'll jump in the 60-64C range +/-.

Now, I just built a "cheaper/lesser equipped" IS7 based board running a 2.4ghz P4 ... and it looks like I'm getting 5-8C lower than my IC7-G. I think that might be because of the hard drives and other things in my IC7 generating more heat plus the 2.8 ... but that is only ME and I know crap!! ;) 

Also, cases -- IF I were to choose again (which I'm going to build another one of these guys), I'll be choosing the Thermaltake XASER III 2000a OR a Lian-Li case. Don't know which model on the Lian-Li yet ... maybe the 6089.

and, for the record, both my Abit systems seem to be working very well.. very happy with them.

Okay so your setup is pretty close to mine.. you are saying then I shouldn't be worried about the CPU temp running idle at about 45C and then when under load running at about 60-65C ??

Altough it seams a bit warm your not even close from burning your P4. Just put your alarm a 70C. My P4 2.26 533mhz is runnin at 40 under load. I didnt used my new P4 2.6c so i cant tell you what the temps is...
June 27, 2003 9:06:34 PM

well, it would be good for you to take a look at all the temp threads/postings and just get an idea of what is happening. at one point, they even bumped (abit that is) up the bios setting to 80C (i think) so that it gives extra room for it to shut down. I don't recall what is on the 1.4 bios and now the 1.5 bios just came out but i haven't installed yet.

so, i think you should be ok -- sounds like your idle temp is pretty good and that 15-20C jump SUCKS but I think that's just the way it is. And, I think you are running stock HSF (right?) ... if so, you *MIGHT* think about going to a 3rd party HSF (like a Swiftech, Thermalright 900u, etc...) with a 92mm fan that outputs well... and see if that helps just a little. PLUS, I'd probably go with that Artic Silver 3 stuff ....

what does the p4 2.8c burn up at? and what would burn up first, the CPU, the motherboard, or the other components like the video and sound cards?

Also would a card burning up damage your PSU ??

P4's are supposed to have an automatic shutdown if they get too hot.. where is the setting to enable this? or is it always enabled by default? and do you know what temp it shuts down at?
