* Mini Guide* - Improved Socket 775 Heatsink Retention

[Mr Fox]

I have hated Intel's Stock Socket 775 heatsink retention scheme since I switched to C2D and C2Q.....

This is the way that I have found to work around this issue, and assure that the heatsink is retained, and that the heatsink base is assured good balanced contact with the IHS of the CPU.

Thru this method I have solved the issue of Half Assed Design, and the issues that come from it.


4x Nylon 4-40 x 1/2 Pan Slotted Machine Screws
4x Nylon 4-40 Hex Nuts
8x Nylon 3/8" OD Washers

Nylon is best as it has some give, and is non conductive... No chance of shorting.....

The Screws need to be mounted thru the back some people might want to put a little thermal grease near where the head goes thru the PCB. This helps hold the screws while you turn the MOBO.

On the CPU side each screw needs 2 washers to assure proper clearance of brackets over the Caps.

Once you get the heatsink fit properly to the screws use 4 nuts to tighten the heatsink down, be careful to balance the tension applied, and tighten each screw a little at a time so as not to bind the HSF.


This gives consistent temps, and assures no clips releasing.

This is my 3060 @ 3Ghz. on P5WDH

These will also work to retain damn near anything to a MOBO.... NB and SB Heatsinks come to mind.

Is the only thing you need btw, normal screws do the job as long as you don't use metal rings.

I have always hated the Socket 775 retention but after installing the stock HSF on my new processor I kind of changed my mind. This was the first time the process went smooth as silk. I click each one down and then immediately locked into place. Maybe I just got lucky.

Fox,
Your method will work. I've seen many variations of it, but for a few bucks more I prefer the Thermalright Bolt-Thru Kit.

This detailed guide can be adapted to just about any heatsink that uses the standard Intel pins for mounting the heatsink...it uses metal screws, as well.

why can't we just use metal screws and metal washers/nuts?

You can .. But I like Nylon for a few reasons.

It is non-conductive, and it has some give to it, and the nuts will stay tight once they are tight.

my way the screws only protrude just far enough, and by placing the washers on the top side you get proper clearance over the Capacitors.

Is there different size name for 4-40? Google search seems to find what I need at Amazon but browsing at Lowes or Home Depot 4-40 is a tiny screw/nut
