Need replacement heatsink for HP a6400f that uses same screw holes as coolermaster that came with it

I've got an HP a6400f where I've replaced the Pentium dual core with a
C2Q Q6600 and I want to put a better CPU heatsink/cooler in it. Does
anyone know of one that will be a direct replacement for the
coolermaster heatsink/fan that is used by HP on this machine? I've
upgraded the PSU in the a6400f to an ANTEC Earthwatts 500 watt PSU.
The stock PSU was 250 watts.

FYI, I wouldn't have tried using the stock a6400f HP/coolermaster
heatsink on the Q6600 except that the HP sells a machine, the a6554f,
which has the same case, motherboard, and heatsink/fan as the a6400f
but comes with a Q6600 as the stock CPU and a 300 watt PSU.

Does anyone know of a replacement CPU heatsink/fan which will use the
screw holes from the coolermaster fan that HP seems to use on most of
it's machines. I'd like to avoid having to remove the motherboard and
swap out the backplate for the heatsink. IIRC, the fan connector is 3
wire.

TIA

Motherboard - IPIBL-LB microATX ?

http://www.computerforum.com/attach...63d1243632201-question-asus-ipibl-lb-mobo.jpg

I compared to another retail microATX LGA775 motherboard, and the keepout
pattern ("X" with four screw holes) appears to be the same. So an
ordinary LGA775 cooler should work, whatever you choose to buy.

I wasn't able to find the pictured original cooler, so I don't know what
that item is. I have a Coolermaster on my present system, and that
one screws into place, and is a pain to install. I have to take the
computer all apart to undo it. There are nuts on the back, which hold
the stiffener plate.

Yes, that's the motherboard used in both the a6400f and the a6554f.
It's the Asus IPIBL-LB also known as HP/Compaq Benicia-GL8E

Here's the a6400f specs

http://h10025.www1.hp.com/ewfrf/wc/...ry&lc=en&dlc=en&cc=us&product=3686671&lang=en

and here's the a6554f specs

http://h10025.www1.hp.com/ewfrf/wc/...ry&lc=en&dlc=en&cc=us&lang=en&product=3752852

They both use the 5187-8413 heatsink/fan. The following part info
shows that the same heatsink/fan is used for everything from celeron's
to C2Q Q9550.

I was hopeing to find a heatsink that would screw into the backplate
from the old one.

It could be an AVC brand cooler. The nuts on the backing plate might be captive.
As long as the backing plate uses adhesive, it would stay put until another
heatsink is attached. (On my Coolermaster, the nuts are not captive, and they'll
fall off.)

The HP "Class F" heatsink/fan is pictured here for comparison. I'm guessing
the screws are the same type as the AVC example.

The AVC website itself seems to be useless. I suspect they manufacture more OEM
product for Intel or AMD, than they do retail heatsinks like this one. This one
is spring loaded, to control the normal force loading of the heatsink on the CPU.

If you find a replacement LGA775 cooler, the center to center spacing
is likely to be the same, but there is no guarantee on screw thread pitch, diameter
etc.

For example, my Coolermaster screws look a bit similar to the screws on your
heatsink, but the length of the screw, and the thickness of the backing
plate could be different. Meaning that even if the screw was the same thread
pitch, it might not be long enough to reach. There are lots of potential
"gotchas" with just bolting another cooler into the old backing plate.

http://www.coolermaster-usa.com/product.php?category_id=1623&product_id=2729

So you could purchase another cooler, and need to take the thing all apart
anyway.

The problem with the HP information, is searching backwards, and seeing in
totality, what heatsink options HP has for LGA775. HP probably has a few BTX
style computers, and the heatsink from those would not be suitable. Class F
seems to be for Intel. Class E seems to be coolers for AMD. I don't know if
the "Class" thing refers to the socket type, or what it might be referring to.

I don't see a way right now, to guarantee a solution.
