P4 3.2 blew up ! temperature @ 70 C help..

hi..

i just bought some new parts..

p4 3.2 w/ 800 fsb (northwood) using stock intel fan and some arctic thermal paste
msi pt800 neo
radeon 9800 pro all in wonder
sound blaster audigy
1 gb ddr ram

a couple of days ago.. i was playin games, and boom, the computer shut down... i was like , wtf ? turned it back on, started playing, and peice of s*** turned off again

so.. one more time. i turn it on, try to play games, THIS TIME the f*in power supply BLOWS UP
SMOKE COMIN OUT
BURNING SMELL

i freaked out, i thought i fried my s*** for sure. so my question is... what is the f*in deal ?! i got new parts w/ plenty of cooling, i left the case completely open on the side and i got a huge fan blowin into it.

last time i checked , the system temperature was around 30-40 (idle-load)
the CPU TEMP ranged from 51 to 72!! I think my power supply blew up when it got to 72. ....

i dont get it , why would this happen, the install was correct, everything fit into place, nothign was loose, the heatsink was touchin the cpu... i dont get it.. why why why ??

luckily, my mobo and cpu didnt get fried, i went and returned my case and got a new one (with a new power supply) and i rigged it all back up again.

still the same problems, nothing froze and shut down, but the temperatures are very high when i play games

cpu temps range from 51 to 70. as soon as it reaches 70, i close the game and the temp drops dramatically

i use the motherboard software to check cpu temps and system temps as well as fan speeds

the intel fan ranges from 2500 to 4000 rpm

i dont have any internal fans yet since i have this huge ass fan blowin into my case

so... i just dont get it, shud have I not bought a p4 3.2 ?

i had a p4 2.0 ghz 533 fsb (northwood also) and the cpu temps ranged from 30-40

i was really suprised when my idle temp is around 50 ...

am I alone?

my cousin has a p4 2.8 northwood 800 fsb and he gets similar problems like i did.. really high temps...

we both get scared to play games now, and what the hell is the point of gettin a powerful system if u cant use it

sigh

First of all, you need proper case cooling. 2 or more 80mm fans (not including the psu fan) are needed. Have you gotten an new psu?

Does your motherboard actually support a 800mhz fsb processor? I havent heard of the pt800 neo. Is your processor a E or C class?

Proper case cooling is a must. Your motherboard could be reporting the wrong temps too. An thermal probe may be needed.

as for proper case cooling, i dont think thats needed right now, as i got a big.. huge.. fan blowing into the case, (like 200 mm)

whats a psu?

my motherboard does support 800 fsb

here is the ebay link for my CPU
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=6705841430

it is a 3.2E (what is the difference between a C and E ?)

L2 Cache Size: 1 MB
Processor Socket: Intel Socket 478
Bus Speed: 800 MHz
Processor Class: Intel Pentium 4 w/ HT Technology
Processor Speed: 3.2 GHz

my case has a thermal probe, the temps ranged from 32-41

thanks

You need better case cooling to get the heat away from the cpu (aka processor) and to get cooler air in the case. It doesn't matter if you have a 300mm fan blowing in air, if you can't get it out, temps will build up.
PSU = power supply unit. What wattage are you using?
The E class chips have 1MB of L2 cache and are called prescotts. These chips run much hotter than the C class northwoods. 55C isn't bad for one of these chips.
What kind of heatsink and fan are you using and what shape were the heatsink and processor core in when you put it in?

my motherboard is actually MSI PT880 NEO, my mistake

as for the psu, its 450 watts, and it is new because I the new case replaced

im using the intel stock fan and heatsink that came w/ the processor

I read some other threads in this forum and I think my problem is that I may have put too much of the paste on the cpu.

This may or may not be the case, i didnt put tooooo much, but its my only guess cause I did everything else right

my cpu is 51 idle, and 65-70 for high load (games)

If I get down to 55 for high load, I'll be mucho satisfied

I'll buy some 80 mm fans like you suggested, I think i can fit in 4

1 in the front, 2 on the back, 1 on the side

on the side of the case, there is this CUP shaped object connected to it. im guessing some kind of fan goes in there, but I dont know how to utilize that cup object

JayDubya · Posted: Mon Sep 20, 2004 1:05 am Post subject:

That cup is probably a duct used to bring fresh air in.

To put on the thermal paste, you must put it on in a very thin layer and spread it out with a flat object. Spread it out so you can just barely read the numbers on the processor core.

It would be a good idea to clean the heatsink and processor before you do this again. Use 70% or better isopropyl alcohol and cue-tips.

i dont get how the duct will bring air in, there is no fan connected to it

JayDubya · Posted: Mon Sep 20, 2004 1:26 am Post subject:

It is a duct. Air will be ducted into the fan and pulled in from the fan. That was just a guess of what it is. Do you have a link to the case?

oh and prescott strikes again!!!!!!
pt880 is via's latest intel 478 chipset, featuring dual channel.

check the board for any blown capacitors.
sounds to me that the origanal psu was too weak, so the prescott fried it.

what does a blown capacitor look like?

I dont think the psu was too weak because I noticed some problems with the assembly the first time

the first time i assembled it, I put too much paste (insanely too much) and the heatsink didnt seam like it was touchin the CPU completely. I noticed that later and fixed the heatsink problem, but there was still way to much paste. I think that may have caused the psu to blow up

the second time i assembled it, i used that isopropanol cleaner on the cpu, but not on the heatsink, so temperatures are still kinda high-- i think if i go back and clean them both i will get better temps.

also need to get 4 fans, i took a pic of the case with the duct, maybe you can figure out how I can use that

thanks

sorry for multiple posts, another pic

That duct is meant to bring in fresh air for the processor. It should fit right over the heatsink and fan.

What brand of psu do you have? Quality means alot more than quantity.
I can almost guarantee that your psu blew because of too much heat. Most of those caps can't take any more than 75-80C.

That one fan won't do a thing. I wouldn't even run your computer without some case fans. The only thing that is happening is that heat is constantly building up with no place to go. It would be a good idea to put a blowhole in the top of the case too.

Do you know what a regular capacitor looks like? They are a round cylindrical object. They are usually taller than they are wide. if you look, it will have a number measured in uF. A blown one may leak some sort of chemical. Don't touch it because it can be harmful to you.

so far these guys are pointing you in the right direction. And yes that duct is for providing fresh air to the cpu (I believe that Intel says that duct is needed for a prescott. I forget the actual wording though.) Also as these gentlemen have pointed out that you NEED case ventilation. As the heat has no where to go. You may need to get a better heatsink and fan for that cpu. My suggestions would be a thermalright or a swiftech.

May be overstating the obvious, but you say you're using the stock HSF AND thermal paste?
Did you clean the Intel thermal pad residue from the HSF and CPU before you used the paste?

^^^^good point

im getting mad

i cleaned up the CPU and heat sink from all the excess thermal paste that was on there before.

I added two fans,

120 mm fan in the front, blowing air inside
80 mm fan on the back, sucking in air from inside, blowing outside

I closed the case, the duct was pointing towards the heatsink, so it could get fresh air.

the results were horrible

i was getting really high cpu temperatures, up to 62-63.
i took out the side of the case, temperatures dropped dramatically, but still higher than before, around 55-56.

i dont know what the deal is, I did everything anyone could suggest. I cant believe Im having so much trouble getting decent temps on this machine, its absolutetly rediculous

Only lesson learned from this is to never ever ever buy a prescott. The ebay auction I bought it from never stated it was a prescott, so I thought it was the C version, not E..

sigh

ok time for the facts.

1. You have a MSI motherboard for a P4. I know from experience that they read temps higher than some other boards do. They read about 6-8c higher.
2. You have a Prescott running at 3.2 ghz. This will produce alot of heat.
3. You are using the stock heatsink and fan. Not the ideal cooler for this combo.
4. you still need to add that other 80mm fan at the back.

^^^ agreed

these ARE good chips....dont be som disappointed yet....=] they just require more cooling than the northwood chips
add the extra fan.....get some load temps....and subtract 5 (for the inaccuracy factor)

BINGO!......i bet you'll be fine

I agree with Weaz.

It wouldn't hurt to add that other 80mm fan to exhaust air and create a vacuum. Right now, that duct probably isn't working as well as it should because your 120mm fan is creating postitive pressure inside the case and it may be trying to push some air out that duct.

Known fact: Prescotts are just plain hot. They are much MUCH warmer running than their northwood predecessors. At least your temps seem to have come down quite a bit.

I've always found the Intel coolers, when installed properly, to be very good AT STOCK SPEED.

Having said that, a buddy just installed a 2.4c in a new Abit board and got really high temps with the stock cooler. I suspect the diode wasn't reporting the temps accurately, but the temps still were quite high (60+C) for a 2.4 @ stock speed.

A thermalright cooler dropped the temps nicely.

Another bud has a 2.8c with stock cooler on an Asus board with no problems at all.

Waddayagonnado?

Abit P4 motherboards have one great known flaw: they always read high temps. Temps are much higher (7-12C in many cases) than their actual temps.

These guys are correct on many things....But add the 80mm in the back, for sure. And maybe try this....get a fan speed controller (or a couple 25ohm 2W pots) and put another 80mm over the duct blowing in. Then speed control the duct fan and the 120mm fan. This way you can play with it a bit and find the sweet spot. 2¢

im going to install my other heatsink that runs at 6000 rpm

it has a speed control, ranges from 3000, 4500, 6000 rpm

i used this on my old p4 2.0 and it was great

i also tried this heatsink with this new system, p4 3.2, and thats when my power supply blew up. so im kind of hesitant to try again.. im going to clean up that heat sink and give it another go... unless anyone has a better idea

btw, the thermal paste im usin is the arctive silver 5
the heatsink i will install is the volcano 7+

wish me luck..

another question...
anyone thats runnin p4 2.8+ prescott chips, what are your temps? how many fans? what kind of heatsink are you using?

thanks..
