Hi All,

I just installed a cooler master Aero 4 on my P4S800D-E Deluxe. I have an
Intel P4 3.0Ghz. I also applied some Arctic Silver 5 new compund. What I
noticed is that the HS seems more "loose" than the stock setup. I am not
sure if this is the clamps or that the stock system is very tight. When I
say loose, I dont mean that it seperates from the CPU, but I can fairly
easily "wiggle" the HS. The clamps supplied with the HS dont really lock it
down hard. I suppose my question is : How tight should the HSF be attached
to the P4 (478) CPU??

Thanks
Musty

When Intel works out how tight to make the clamps on the Intel
retail HSF, they take the weight of the HSF into account. The
idea is, they are trying to prevent the HSF from moving, if the
computer receives a mechanical shock.

This slide set should explain their thinking:

The best designed heatsinks use four screws that go through
the motherboard. You can drop a computer equipped with
such a heatsink out of a second story window, and the
HSF will still be in place after the computer has landed :-)

HTH,

Thanks for the response Paul. I am going over the presentation.

I have a second question (and it is really for those who have the Aero 4). I
would like to know, how tight they found the clamps to be. Was it very
tight, tight, moderate???

BTW, I am getting about 91F on idle and about 111F on load (eg morrowind or
RTCW). Again, it is a P4 3.0Ghz Northwood running at factory speeds.

Thanks
Musty.
