Seating the core2 heat sink fan

[Akill]

Hey people, hows it going?

i put the specs together and built a friend a pc the other day he had a decent budget so the cheapy core 2 quad was a must have.

everything went well putting the box together... except the heat sink fan! ive installed one core 2 hsf before and it was a pain, i hate having to do it as it seems to require a phenominal amount of energy to get the pins to actually clip in. needlerss to say i also had trouble putting this HSF on correctly to, it required enough force to scare my friend and i myself as the motherboard did start to bend under the pressure.

Well enough rant heres the problem. the system shuts down soon after booting up. i managed to enter the bios motherboard monitor and saw that the cpu temp rapidly increased from 50c to 100c before shutting down, this happens everytime. i conclude that i must have done something wrong with this HSF. it is in good contact with the cpu and there is the normal amount of thermalpaste u would expect with a factory hsf.

is it possible i have damaged the cpu, and the thermomitor is giving false readings? ive read abit about core2's temperature monitoring method so i doubt i could of damaged the motherboard. my other conclsion is, as i described at the beginning, my complete lack of skill in installing this really irritating clipping method- you guys might fid it good i dont know.

anyway can anyone explain if there is a trick to installing this hsf? if i need to test somehow for cpu damage?

advice appreciatted. i feel like a tard this being the first box ive built which hasnt actually worked. i did have a good record lol

looks like the heatsink is not seated if its doing that.

maybe you should do this with the motherboard removed to stop any flexing you were getting with the board on its mounts.

[Akill]

yea we did have a fair few tries with the motherboard removed. would you recommend trying on a flat surface?

can the cpu get that hot if the hsf isnt perfectly seated? it seems mad how the hsf is now isnt on properly

[GoNz0]

if its shooting up like you say it is then it can only be bad fitment, im assuming you used thermal paste and removed any crap or plastic covers from the heatsink prior to mounting?

yes get it on a worktop and do it, press away to your hearts content

and does the heatsink only fit one way ?

never built a c2d system, but the old AMD heatsinks had a slot cut out and if fitted 180 degrees out the heatsink would sit on a angle missing 99% of the CPU

[Akill]

ahh ill check for the right way round thing. to the eye it all looks pretty much symettrical and the manual doesnt mention anything like that but yes i will have a check. and ill get it all out on my desk and proper jam on it lol

[GoNz0]

well you will see when you take it off if it was fitted or not, but if it shot to 100 degrees c im going for hanging off

[Pob255]

it is symettrical, the 4 push pins go in the 4 holes, that's it for the basic stock HS&F.

I must admit I had the same thing when I first installed my socket775 (pentium D here but it's all the same) the push pins were a real struggle and bent the board enough so that I was worried.
Take it apart, inc takeing out the CPU and reseat the lot out side the case.
Doing it on a flat surface will work well, I'd advise sticking the bit of foam that comes in the motherboard box under it just to protect it.
TIP:
Once you've got it lined up, push in one connector then push in the one diagonally opersit it, then the other two.
Make sure the push pins have gone all the way through, check the back of the motherboard to make sure. (I found on my first try a couple felt solid but when I looked at the back of the motherboard I could see they were not through all the way)
Also if there are any large/sticky up components on the motherboard near one of the push pins, start with that one first.
You can also use a flat bladed screwdriver to get some extra force on to the push pins.
You also might find it goes on far easier a 2nd time (I think intel's thermal paste is spread a bit thick and after a 1st atempt you'll have squeezed some of it out)

[Akill]

how do you mean i will know? ive taken it off previously and the thermalpaste was spread onto the cpu. ive even taken the cpu back out (carefully) and replaced it.. i cant remember why i done that right now it was like 4am when i tried lol.

could it be that when i was attempting to seat the hsf the paste spread but if it wasnt clipped on properly the hsf lost the contact between the chip and the base?

[GoNz0]

well if you already checked it was spread then its very possible for a pin to pop out if not quite in enough to catch.

A few days ago I installed my E6850 and it does take surprisingly alot of pressure to get the clips in. Like POB255 said, push the 1st pin in and then the opposite(diagonally) pin, otherwise if u just push the pins in clockwise or whateva then its almost impossible. U shud hear a nice click when they go in aswell, good luck

[Akill]

thx for the advice pob ill give it a go in a bit

[Pob255]

If you look at the back of the mother board when you push the first of the pins through you'll see how it clips on

[Akill]

Hey guys thx for the help yea it took a bitch to seat it properly but its done! thx alot it was running quad at 29'C :O

[GoNz0]

thats more like it

[UseItNow]

Thanks Pob255, the info on pushing in the opposite pins will certainly help when I come around to installing the E6750 but thats once I've received it.

When ever you tighten any form of clip or bolt whether it's on a pc or a car engine cylinder head etc then always tighten the bolt opposite next, never work clockwise or do one side first.

Glad you got it sorted. Reminds me of the socket A dance of death with the screwdriver for the heatsink clip!
