So, I was thinking about this:

Anyone who updates their PC or builds new PCs often probably has a bunch of Intel stock heatsinks laying around. I know I could find at least 3, probably 4 if I looked around my house enough. This is because when I upgrade my PC, I get a new processor, but I always stick with better aftermarket air cooling (usually a zalman 7K or 9K series) instead of the Intel stock, because, well, to me it is worth the extra money to get my CPU 25 degrees cooler and to get to that next level of air overclocking.

The Intel stock LGA775 cooler is interesting for me. It isn't quite worthless enough for me to toss it into the garbage, but at the same time I would never depend on it for an overclocking rig. So they sit in drawers around my house.

So today I was thinking, what if I did this:

1) Find 2 of the Intel stock HSFs I have around. We will call them HSF 1 and HSF 2.

2) Take the push pin mounting assembly off of HSF 1. Take the fan off of HSF 2.

3) Get out the soldering gun. Neatly solder the contact base of HSF 1 to the now-bare top of HSF 2.

4) Let it cure.

5) Bam. You now have 2 Intel stock heatsinks stapled together, one on top of the other, under one Intel stock fan. The metal solder conducts the heat from the bottom HS to the top HS, and the fan which you left intact on the top HS adds cooling additional power.

This jury-rigged contraption is still mountable on the mobo because you left the push pins on the bottom HSF intact.

In theory you now have double the surface area and double the heat dispersion compared to a single Intel stock hsf.

I dunno, it's just something I was thinking about. I suck horribly at drawing, so no picture to express my thoughts, but hopefully my description is good enough that you all can grasp the point.

Thoughts, opinions? Should I try it or am I wasting my time?

Why not try it if you have all the stuff.

Do it, test it, post results, post pics. In this thread.

It will probably be better than the original stock cooler, but not by much.

Also, the fan on the heatsin will now be futher above the board and will cool board components less well than before.

A cheap 3rd party heatsink will still outperform it.

Well I think If you get a bigger fan like a 120 x 38 and rig it to the side. so it's blowing sideways instead of downwards. Good idea.

I like that idea. Dunno about a 120 but I have a 90mm case fan that I could rig to blow on the side.

Also I was thinking about mixing a little bit of thermal paste in with the solder that holds the two hs together, to get the most out of the bond.

problem is that intel stock coolers don't have a fully solid copper slug in them. They're hollowed out somewhat. You'd need to fill that entire cavity w/ solder and @ that point it's just act as a thermal capacitor rather a conductor since tin and lead are poor conductors as far as metals go.

I was thinking about that, it is 100% true that lead and tin are bad conductors.

But on the other hand I think some modern day solder might contain copper and silver in fair amounts, both of which would do a far better job.

DesertRat

You'd still have a glob of poorly conductive(in relation to the HSF) metal sitting in there. If you could make a silver slug and then solder to that it'd probably work, but I would think it'd hardly be wroth the time and cost.

It'd still be cool to see it done, regardless of it's efficiency.

edit:

IDEA!

You could fill the hollowed out part w/ TIM maybe and solder the aluminum together. Then again the thermal paste is hardly an optimal idea, but I'd imagine it would be cheaper than a couple tubes of solder or a custom made small copper or silver slug for a project like this.
