hi, need help!!

[trigga]

Hi, i bought a P4 FSB800 with HT, 512ddr ram at DDR400Mhz, MSI Neo motherboard(the cheapest one supporting HT at the time), ATI Radeon 9600PRO, 120Gb HD, and the cheapest case for it

when i first bought it, the CPU temp goes to 63 and it would restart by itself (i think that's y it restarts) and this is when i used the stock fan that came with the CPU, so after that, i have always kept one side of the case open for air circulation, and the temp goes to 59/60 ish, and it doesn't restart anymore
just recently, i bought a Vantech Aeroflow 2 for my CPU, i applied the thermal compound and all, but when i close the case, the temp goes to 60/61 still!, i have no idea y... so now when i keep one side of the case open, it stays at 57/58 ish . i mean...the new fan is pretty good in my opinion, can someone help me out??

btw, nothing is overclocked, and with teh stock fan the RPM is approx 2600-2700rpm, and with Vantech Aeroflow, the RPM is 4400 -4560rpm

any help would be appreciated!

How are you applying the termal paste?

 

[trigga]

oh ic ic, i just read up on how to apply the paste, and yeah i dumped a whole lot on, that's prolly y the temp goes high, but the website which said to clean the surface of the cpu die and the heat sink thoroughly, is it safe to scrape the cpu die?

i am sorry to reply so late, couldn't get online.
but your help is greatly appreciated

The P4 cpus have a heat spreader already on them, so that big metal part on top of the cpu isn't actually the cpu die. Hence it is ok to "scrape" it, however, this shouldn't be necessary. Cleaning the excess thermal paste should be pretty easy to do with a lint-free cloth. As I'm you've read now, you only need a very small amount of thermal paste. Just spread that amount around on the top of the heat spreader (I used the back of a corkboard pin (those round ones with a slightly curved back) - it worked perfectly. When you clamp the heatsink onto the motherboard (however it works for that heatsink), the thermal paste should find its way into the slight imperfections of the heatsink and heat spreader.

Never use a metal object or anything else that can scratch the CPU or the heatsink base. Just use a cloth that does not leave anything behind (like the ones used for cleaning lenses) and some 91% alcohol and clean both the CPU and the heatsink.
Scratching the surfaces will do the opposite of what you are trying to achieve (increased heat transfer).

What type of P4 is this, Northwood or Prescott?

What is the room temperature?

How many case fans do you have?

hi
i dunno how to check if it is northwood or prescott
the room temperature is around 20-25
and i have 0 case fans, haha
thanx

Umm... case fans are good... you should always have at least 1 case fan - even dell ships their pcs with 1 case fan . Even the xbox comes with a case fan (albeit no cpu fan).

You'll find most people have 2-3 case fans on these forums plus (usually) a 2 fan psu. It's very unwise not to have case fans. Unless you have no case and have your parts just sitting on the desk. Then I can understand you having no case fans .

case fans duh!!! (slaps forhead)

Download CPU-Z from this link and run it. It will tell you what kind of CPU you have. A Prescott runs hotter.

Not having any case fans explains a lot!
Just wondering what you expected!

Yah, case fans are a good thing... lol. Also, do like the AS5 instructions say and put a bit in the middle and then put the HSF on top of it to flatten it out. Spreading it out over the heatspreader is not only a waste (there's much less heat on the corners), but it allows particles to fall into the paste before you get the HSF on, and its easier to trap air bubbles in the paste.

 

[trigga]

yes i understand case fans r important, but the thing is, i leave one side of the case open at all times...and the temperatures still goes to 53 (this is after i applied the thermal compound correctly, thanx )
so if i get a case fan and close the case, i dunno if that will beat no case fan but 1 side of teh case open...
shrug

oh and i d/l that cpu tester thingy, it is Northwood

 

[Degrador]

How are you testing these temps, btw? If you're doing it through the bios then what you're getting is load temps. For some reason bioses run the cpu at 100%, so you can't get accurate idle temps out of that.

 

[trigga]

yeah i am reading the temp thro the bios
man, good to hear that bios runs the cpu at 100%...
