CPU Overheating?

by bait28 / September 29, 2012 3:26 PM PDT

I am offically lost on this. I have a pentium 4 HT at 3.6 ghz thats been running fine all year until now. Suddenly it's just extremely overheating. This server is maintinenced regularly and has no dust in it. I have removed the heatsink, cleaned the CPU and heat sink with alchol and then applied Artic Silver thermal Paste(around the size of a BB) then screwed it back down. And in about 10 seconds off booting it's back to 90C. Why is this happening?

You used rubbing alcohol.......that stuff has oil in it.
Thermal paste........you don't need much but it's best to spread it out a little.
Is the fan working?
The heat sink is spring mounted and you ran the screws down tight.

It's all fine

I used Cleaning alchol that is 70% Isopropyl(Pure, nothing else)
Thermal paste was spread out, and is in place well
Fan is working, otherwise the Mobo would have freaked out. You can hear it go to full RPM really fast
My heat sink is spring mounted with a backplate, and it is tightened down to what it sould be.

70% iso is normally rubbing alky.......it has oil in it.

What you looking for is 91% iso.......sometimes called surgical fluid.......no oil.

Thermal paste......some flavors of that stuff require multiple heating/cooling cycles to become effective.

None of that explains why this suddenly started.

It looks like the stock hsf.....even when brand new and super clean is marginal under heavy load.
I suppose it would not take much build up to push it over the edge.

Hot while just in bios

Well it runs hot while just sitting in the bios with both coolers. so who knows.

options. Which HS FAN are you using? Almost sounds like it's still not making full contact.

By the way ....what were the TEMPs before this happened ?

Tomshardware was all over that one. It is one hot CPU.

Nothing's wrong here, that is one hot CPU.

http://www.youtube.com/watch?v=N1hg1zf7rrY and many other pages talked about it long ago.

Your average Joe may not know it was a problem child.

not locking in place and making full contact.

If it were mine and I wanted to try further to fix, I'd get an aftermarket HS Fan ...like Xigmatek that has a backplate to secure the HS Fan. The original equipment HS fans can pop loose and you'd never know unless you're check temps or system performance. 10 to 20 degree difference is worth the money if it keeps the CPU running cooler at higher and greater stability.

I know the P4 ran hot, i'm just saying it used to run hot underload. now it runs to 90C 10 seconda fter pressing the power button.

Mine isn't a Pin fan, mine is a screw with backplate, so i know it's not popping off. i've put the stock fan back in and it runs cooler? but still overheats after a few minutes just ideling in the bios. i may have to put my watercooling system back into this server. i thought be cause i was nolonger running it a 4.2 Ghz, water cooling wasn't needed. guess i was wrong.

Ahh, overclocked.

That can damage the chip. Try another one.

Remove cpu and clean underneath
by Willy / October 1, 2012 3:23 AM PDT
In reply to: CPU Overheating?

Remove cpu and place aside and now clean the socket and immediate area around socket. The sensor itself could be dust clogged or simply dirty. It doesn't have to be huge dirt pile but one that reduces airflow around the area. In other words the sensor itself is the immediate area of concern rather than the cpu. Also, don't assume because the fan is running that it isn't kicking-in the variable speed/RPM it needs if so optioned. Fans do wear down and another one rated for that cpu would strongly be advised. I hope besides my comments and others will help resolve your problem.

The P4HT at 3.6 GHz is an anomaly.
by R. Proffitt Forum moderator / October 1, 2012 3:27 AM PDT

It was discussed about 10 years ago and frankly I'd underclock it to keep it running today. HOWEVER it looks like they overclocked it and may have suffered some damage.

I see a 60 buck desktop with the P4 at 3.4GHz at http://www.geeks.com/details.asp?InvtId=WSYS199-NOHDD-PB-2R

Given what the CPU alone costs you might scavenge this slightly lower clock speed CPU (which I think is a better idea so you get away from that 3.6 troublemaker CPU.)

It may also have the real Intel HSF.

1st fan is an intel stock cooler, second is a AVC cooler with a 90mm 3,500 rpm fan.

before this happened temps were around 40C idle and 50C underload.

it WAS oc'ed previously. that was 3 years ago, it's been running stock speeds since it went into the Server. which was 2 years ago.

But some part has failed. What you will encounter are folk that can't accept that. At some point you have to give them space and time to figure that out.

It is INFACT running hot. All the heat is staying at the base of the heat sink and not getting to the heatsink fast enough. The fan is a Delta running 6k rpms. that didn't even fix it.

Don't remember much about that CPU....

does it have a CPU heat spreader ?

Condolences on the 6K Delta fan, that's a screamer from the old days.

i don't see much performance difference in the two. definatly will beat this 2GHz cpu i'm using as a spare.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
