ok, 4 those of u who have been reading my posts, i have been trying to cool down my cpu. i have managed to cool down the processor considerably by opening my window, but we have had 90% humidity the past few days so i decided to close it. i managed to get my cpu idle down to 50 (57 at full load). recently, i was browsing the intel website and realized the max junction temp is 67C(p4 1.8a). Ok, now im really starting to worry. So i decide to check their thermal specs and it says that the max temp for p4 1.8 is 77c(it doesnt specify 1.8 or 1.8a)
am i ok. sorry if this has already been answered. I attempted to dig up some info from the forum, but came up empty handed.
the crazy thing is, my cpu fan previously averaged about 3000rpm, but it recently dropped down to 2500 avg. IF the cpu was too hot, wouldnt the cpu fan attempt to compensate for the higher temp?
sorry for all the questions!

For a P4 that is hot! WHat kinda heatsink you got running?

Also the fan doesn't compensate unless it's a 'smart' fan. Most fans aren't, so the slowdown could be for a variety of reasons. If you got a weak PSU, or it could be burning out. Stuff like that.

i have the stock intel HS and HSF. Tomorrow, i am going to buy some thermal paste and reseat the HSF. Hopefully that will help. my comp has been extremely stable(no crashes whatsoever, even at max load)
i hope my CPU doesnt croak prematurely on me
:( :(
if these temps are indeed too hot, do i risk damaging my mobo? i sure dont want to pay another 200 plus 100 or so for a new cpu and mobo

Wow thats hot. Maybe a motherboard issue with the fan speeds showing lower and all. Not detecting properly or something. I'd try a thermal sensor thingy see ehat it's reading the temps at.

i just did some searching regarding my mobo, and quite a few ppl say that the mobo temp reading is high. I have been using fuzzy logic(windows software program) to evaluate my pc. the diff between the fuzzy logic temp and bios temp is 0 (they are identical).

ok, here's what i did. I opened up my case( with the comp on, tsk tsk;) ) and i touched the HS. its absolutely cool to the touch, not even warm. i have come to the conclusion that the temps i have been given are not accurate. If the comp was running at 50C (something like 129F) the HS would have to at least be warm. This is some werid stuff fellas!

TNG (thenewguy) was there any change in temps after you opened the case? What are the locations of your fans and the direction of air flow? Example; 2x 80mm lower front in, 2x 80mm upper rear out, 1 92mm blowhole out. If you dont know there are usually direction arrows on the fans that show rotation direction and airflow direction.
If you are going to unmount the HS maybe you should look into buying a after market HS instead of reseating the stock one. Also look at this thread for info about thrermal compounds and this site for instructions on applying thermal paste.

i have two 80mm fans in the front section of the case, blowing air in, then i have two 80mm fans in the mid rear of the case blowing out, plus a 90mm fan at the top rear blowing out and a side blowhole fan (80mm) blowing into the case( plus two fans on the power supply, one 80mm and one 90mm)
there is no change in temp when opening the case. thanks for the links tismedt, they were a great help. :)

even with my crappy setup (stock case, no majorly powerful fans) i get 30*C (no load) on air. i also use the stock intel hsf. i took a picture a while back when my case was a mess(http://mywebpages.comcast.net/localgod84/aboutme/computer.jpg) and i still got temps about 33-35*C with no load... have you reseated the hsf? as3 also helps slightly... i would think that the hs would be slightly warm at least if it was making good contact with your processor heat spreader when it's at that high of a temp. let us know what it is like after you reseat it...

There are some motherboard that read temps too high. The IT7 is known to read up to 10-15 degrees higher than it should. Yours might have the same issue, if it does, its ok. Note that software programs get the temp from the motherboard, so its gonna be the same as the bios...

Other than that try reseating. If youre confident that its seated properly and the system is stable then you shouldnt have to worry about it. Probably a mobo issue.

the system is very stable. I have had no crashes whatsoever(even when running Winamp and the AVS component for 30 min straight). I am starting to think its my mobo, since other people have the same problem. I also play Urban Terror for hours on end and it seems stable as well.

Illah: i believe my HSF is a smartfan. Usually, as the temp rises, so does the RPM of the fan.
