Re: Dodgy retail Intel HSF
I would just buy a decent aftermarket sink, like the Artic Cooler Freezer Pro:

For the price its not worth trying to get better cooling with the stock HS/FAN.

Re: Dodgy retail Intel HSF
I agree with what Stormy has suggested.
The intel HSF are not the best out there for cooling and run at higher temps than a lot of the better third party coolers such as the Arctic Cooler. A few websites report that the intel cooler runs at about 54-56 degrees.
Best Regards,

Artic Cooler Freezer 7 a go go 3rded
Re: Dodgy retail Intel HSF
Thanks for the replies. I never really expected much from the stock cooler but i at least expected it to make propper contact with the cpu. Will check out the arctic freezer.

Re: Dodgy retail Intel HSF
The point is though he shouldnt need to buy an aftermarket one. If there is a problem with the one that was supplied with the cpu it should be changed, and it seems there is as if you check out some reviews you will find the stock cooler should give a lower temperature.

There isnt, when its used as supplied (i.e. with a 2mm thick bit of transfer pad) As the OP has admitted removing same, this obviously brings to light the poor quality control that can result in a signifcanly recessed contact area. However, as supplied, it worked fine, and with a similar thickness of transfer compound would continue to. Although its not ideal, intel will get the cheapest heatsinks that work.
Re: Dodgy retail Intel HSF
My first thoughts were along the lines of nickp8 but you make an interesting point herulach about the transfer pad. I suppose technically you are right I suppose i just figured that at the very least quality control would result in a flat base.
Splashed out and ordered a ninja scythe. Although not from scan unfortunately cause I while I have not problems with city link i cant really justify another day off work and delivery to work is not an option at the moment. At least with royal mail/parcelforce i can get it at the local post office. Delivery is not really all that cost effective for small orders to NI. Not really complaining though as on the whole have been more than happy with any recent dealings with Scan.

Re: Dodgy retail Intel HSF
The Ninja should do you fine - but remember that C2D's and Quads use a different method of Arctic Silver application from the old 'grain of rice - thin layer' method we all remember - they do tend to need a bit more:

Re: Dodgy retail Intel HSF
Many thanks for the links Addywebb.
I had found them when i was first installing the CPU but had forgotten about them in the meantime. It is interesting as I would have thought that the entire metal cover that these chips have is a conductor and the more of it that you connect to the HSF the better. I suppose sticking a dollop in the centre allows it to be spread out by force of attaching the HSF. It does say it takes 200 hrs to reach maximum conduction. Also i suppose that the HSF is probably more conductive so ideally it should take the heat away directly from above the actual cpu before it spreads elsewhere on the metal cover.

Re: Dodgy retail Intel HSF
The Intel HS/Fan with the C2D's is actually pretty and a vst improvement than the earlier generations.
Maybe it wasnt completely flat but...by your own admission, you put a 'dollop' of AS5 on.
Dya know thats just as bad as using no Thermal COmpound at all?
Re: Dodgy retail Intel HSF
Actually the only reason I put a 'dollop' of AS5 on is that if I put a small amount the HSF does not make actual contact with the cpu other than at the very edge of the circular base, this is what gave me temps in excess of 80C !!!.
Re: Dodgy retail Intel HSF
Just dug out my intell stock 775 cooler to look at it (after scrapeing off the remains of the paste, intel use a thick plasticy paste not a pad on these)
The base looks just like this one
There's no visable lip around the circular copper base, I did a quick eyeball inspection with the edge of a steel rule and while it's not 100% flat (the middle and edges are very slightly raised) and I can see circular milling marks, but there's deffinately no lip.
it does sound like a dodgy HS&F that should never of got through Quallity control, sounds like you were unlucky.
It should go back as an RMA as it does sound like there's a fault but I wouldn't say it's worth the hassle, a bit of fine grit wet and dry paper and a small flat wooden block should sort it out or better yet replaceing it for something better as you have done. ;)
Still good to know if anyone else gets this problem.
EDIT: on the intell stock cooler, after looking at it and the slight lapping I gave my p4 d (granted not a c2d or qc but still the same basic chip structure)
I lapped my chip after I took the stock cooler off to replace it with a arctic cooler Freezer7pro. when I did this I noticed the paste on the stock cooler had been squeezed to almost nothing at the edges and was still thick in the middle, Lapping confurmed that the cpu heat spreader was rather concave.
I'm not surpirsed intell use nearly 1mm of thermal compound not so much as to remove air pockets but to form a heat transfur medium between the two far from flat surfaces.
I can also forsee that useing the tiny amounts of arctic silzer specified could cause problems, if there's less than enough paste to phsyically conect the 2 surfaces it will do nothing.
Of course the principle behind thermal compound is not to fill in gaps left by unflat surfaces in the first place. :rolleyes:
