My Intel socket 478 HSF is not working

http://www.heatsinkfactory.com/cpu-retainer-clips-intel-pentium-4-478.html

That would be for an AOpen AX4SPE-UN motherboard, because it has a Socket 478 processor socket.

I had it happen to an old mobo in the past, with a Socket 478 processor socket; and no clips.

I used a straight piece of coat hanger, and went from hole to hole, on one side.

http://www.ebay.com/itm/P4-Socket-478-Intel-CPU-Retention-Retainer-Bracket-/140647148266?pt=US_Fan_Heatsin_Brackets_Accs&hash=item20bf392aea

Had a slight bend in the middle, and this bend went partially across one side of the finned Heatsink.

Small piece of coat hanger again, on the other side.
Cut to the right length, and with the correct bend, the two pieces of coat hanger, put even pressure down on the finned Heatsink.

Problem is they twisted. The pressure on the bent part against the Heatsink, made them want to spin up away, from the Heatsink.
So I added a piece of coat hanger on each side, to keep the side coat hanger pieces from twisting.

Hard to explain, and looked like something from Dr.Frankenstein's laboratory.

Worked though.

(Too much pressure, and it will break the plastic retention bracket on the motherboard.
Not even pressure on both sides, and Heatsink will not sit flat on Processor. This = No.
You just have to 'dial it in', (Coat hanger pieces), or use the correct part/s)

Just google "socket 478 cooler"
I found these on amazon
http://www.amazon.co.uk/s/ref=nb_sb_ss_i_2_11?url=search-alias%3Daps&field-keywords=socket+478+cooler&sprefix=socket+478+

There are some from £8.50 including postage

Lots on ebay also

Sounds like the CPU HSF is loose or has stopped
The HSF.. heat sink and fan needs to be running or the motherboard sensors will just shut the computer down.
This board in an intel LGA775 and uses this type of CPU cooler

You can get a new 1 for under £10 and they are not to hard to fit

it will clip down so it is tight. You can get any cooler you like as long as it is for that chip. So find a cpu cooler that is for your socket type of pentium 4

So you need to find a cooler which is 478 compatible (478 is the socket type)

according to the manufacturer:
Support Socket 478 for Intel(R) Pentium(R) 4 1.5GHz~3.06GHz or faster Processor
Support Intel(R) Hyper-Threading Technology CPU
400/533MHz system interface speed
any socket 478 processor with a 400 or 533 bus speed should work.

it defend to your processor is for socket 478 motherboard and you going to upgrade *********** to intel 865 it supposed to be socket 478 too also if not your processor is useless because socket 478 mother is already phase out the new mother now using socket lg775 for intel dual core and quadro core processor

It goes by which socket you have. I am an Intel connoisseur so my knowledge ends with Intel PCs.

If your processor is an early Intel Pentium 4, you will want a socket 478 CPU cooler.

If your processor is a late Intel Pentium 4 or Intel Core 2 Duo/Quad (~2ghz+) you will want a socket 775 CPU cooler. Luckily this socket is still in wide use and many can be found locally or online.

If your processor is an Intel Core i7, you will want a socket 1366 cooler.

Just go to a local PC store and ask for an LGA478, LGA775, or LGA1366 CPU heatsink.

I can tell you that the Socket 478 has been out for production for quite sometime now. Finding a new anything will be rather difficult. My suggestion is to either look on E-Bay for a similar PC that you can get the part(s) from, or check Radio Shack or other electronics outlet store. Good Luck!

Just ask for the fan & heatsink for the 478 socket. Its easily available in the market../

This is an easy one. :)

I am assuming that you're asking about removing your typical P4 HSF.

Direct from Intel's very own website! :)

Good luck and please be careful. *nods*
