What is the best NB HSF?

[superHARD]

I need a good NB HSF for a P4 system. It is the pin mount and not the wire mount if you know what I am talking about.

The stock gigabyte just doesn't want to do 240+ fsb.

So some suggestions and where to get the suggestion would be great!

i have the zalman that mindwreck linked.

mindwreck, your second link is to google

There's also Swiftech's and Microcool's offerings

Shady, the link is actually an invalid one where he must've clicked on the secure http link (https://) unwittingly. Your browser must've redirected to Google But here's the fixed one: linky

I put one these $5 swifty clones on my IS7 @ 275mhz FSB. It is actually very light for a 60mm HS, and I attached with with AS thermal epoxy. You can get one of those and the AS Epoxy for less than a lot of those smaller NB cooler kits. Here's a picture of it installed on the IS7...

Interesting. Did you have to do anything special to get it to mount on the motherboard? You are operating at 275MHz FSB with no fan on that NB cooler? Also, I am curious what HS/F you are using on the processor.

And do you like it?

I like the price! But how well does it work? And will I have to add a fan?

Nope. I just removed the factory HSF, cleaned off the thermal grease on the NB, applied AS adhesive, and put the HS on. I kept some weight on it for a couple of hours, made sure it was sitting straight, then let it sit overnight.

Yes.

I just don't like epoxy. It is too "forever"!!

Or can you get it off?

Thanks Insane3D. I have an IS7 and might give that a try.

From AS:

Varying the ratio of the mix will not significantly affect the curing time, but may affect the strength of the final bond.

Basically, you can make the bond less permanent by messing with the ratios, or introducing non-adhesive AS compound to the mixture. Even with the bond weakened, remember to systematically twist the heatsink rather than pull or slide because glues are designed for tensile strength so twisting should be the best action for removal. You may have to turn a can of compressed air upside down and fire it at the bond for a few seconds to freeze it off in order to weaken it further. To remove remaining epoxy residue, use a rag with acetone or non-fragrance nail polish remover (has acetone) and some elbow grease to get that gunk off.

When choosing thermal adhesive, take into account the risk of getting silver compound onto sensitive components. I would recommend using the Alumina adhesive for your first few applications so that you gain experience with it as Alumina is still much better than thermal tape and only a bit less thermally conductive than AS without being capacitive like AS.

Sorry, I hadn't checked this thread in a couple days. As PliotronX explained, you can vary the AS epoxy's bond strength like the intructions on AS's site mention. I must disagree on the AS epoxy causing problems with board components though. The contact patch is so small, unless you put a ton on, you will be fine. Also, the immediate area around the NB core is simply an organic substrate, similar to a P3, and there is really nothing that would be affected by a little AS epoxy on it.

One more thing. The contact area you use to attach the HS is so small, breaking the bond *should* be fairly easy if you needed to. I agree on the twisting motion being your best bet.

No problem, and feel free to PM me if you have any questions.
