True 120 tightening.

Hi.

Just wondering if it is possible to overtighten the 4 screws and this end up in reducing the cooling performance?

Thanks
Will.

They're only little screws so yes. You can shear the thread.

Just do it until it seems very firm and stable, basically enough to lift the motherboard without it wobbling.

Well it is on and has being for a long time now, just wondered if you can have it too tight where it pushed against the CPU too much and causes the thermal paste to thin out too much?

No, the tighter the better.

I actually have a 2p coin between the bracket and the top of the TRUE base so it gives extra pressure.

Used to use a couple of washers on mine:

I've used the spongy disc that you get in some CD/DVD spindles under my mounting bracket and I kept on turning till the screws bottomed out, that's what you're supposed to do AFAIK.

Just making sure your motherboard isn't bending and you'll be fine.

Will Hub, your classic!

May try a 2p or washer on mine, as even after lapping the cpu and cooler i still get a bit of a temperaure variation on mine between the 2 sets of cores.

Reason I did it to mine, I had 5c variation on 2 cores, added the 2p coin and I only have 3c variation now

This is how mine are at the minute.

4'c between 0 and 1 and 4 between 2 and 3, each individual pair of cores when placed under 100% load tighten up to 68-68-62-62, thats with the cpu and TRUE lapped.

May I ask the vcore your running for 3.8 GHz on air, been sat at 3.6GHz for ages and never tried any higher, however since I now have a TRUE and temps are better; might attempt 3.7 and see how things go (Currently 1.4v BIOS, CPU-Z 1.380). Not had the time of late to stress test in length since replacing the Scythe Infinity.

Oh and that washer idea is a winner, will give that try at some point.

setter · 16 Dec 2008 at 01:20

Vcore in bios of 1.50625, windows idle 1.500v, prime95 load, 1.512v. also ran mine for a while at 3.6ghz with 1.4v.

Pneumonic · 16 Dec 2008 at 09:01

you are safe to 1.55v+ on air if you have nice load temps..

willhub · 16 Dec 2008 at 12:08

With my E8500 at 1.36V it idles at about 40-45 degrees and loads about 60, that ok for 4GHz?

WAH i might try the 2p or washer thing ONE DAY, cba to take PC appart

You don't have to, just loosen the screws, slip the 2p under then tighten it all back down. Job done.

Big.Wayne · 16 Dec 2008 at 13:02

Don't use a 2p, use a washer!

Pneumonic · 16 Dec 2008 at 16:34

washers are easier to ensure that you keep the pressure even because the little screw thing on the X braket can sit in the hole thats on the top side of the heatsink base
