Can I mount a 775 CPU *without* the MB lockdown lever/bracket assembly?

post #1 of 25
Thread Starter 
Hey.

I lapped the bejeezus out of my Q6600 cpu and now the IHS just *BARELY* rises above the surrounding steel 'lever/lockdown assembly' typical of all 775 motherboards.

In fact, after my last mount, I can see etches in the base of my cooler where the steel MB lever/lockdown assembly was contacting the coolers base.

Looking at the AS5 'footprint' after my latest TRUE mount, I can see that the spread of compound is not nearly what it was prior to my lengthy lapping process. The compound is not spread very well ... just sort of hanging around the middle of the IHS whereas before, pre-lapping, it was spread to the extents of the CPU heatspreader.

I've got very good mount pressure as I've modded the TRUE with a bolt-through mount.

...



...

So can I somehow remove the metal lockdown/lever mechanism and sit the cooler directly on the IHS or would this be instant death?



Just curious as to how I could solve this problem as I think the CPU heatspreader is now too short to appropriately make contact with the base of my cooler. Temps are okay but I think they could be better.

Instant death? Prolly not. The only thing you'd have to worry about is that the heatsink isn't making enough pressure for the chip to make contact with the pins on the board and it won't boot and you just get beeps. If you can make it have contact (IE, so it doesn't just lean against the retention bracket), boot into BIOS, check temps. If they're good, I don't see why it would hurt anything.

No, then your cpu wont make contact with the pins.

What is the point of the lever/bracket assembly thing? Does it just help hold the cpu into the socket better?

I think it's mostly to securely press the CPU against the MB pins in the socket.

Also, considering how much pressure is applied through mounts like the above, I was thinking it might be a means of protecting the CPU pins from *too much* pressure.

Dunno, really ... but I know my CPU's IHS is not very accessible now (shaved off a bunch of the CPU surface during my lap).

You can remove it, without issue. You just have to mount your heatsink on a level surface with even force on each side.

I'd say go for it - you've only got a Q6600 to lose!

TBH, weigh up the risks - the main risk you'll have is bending the pins from applying too much downward pressure.

You can shave your bracket too, s1rrah. Not sure if you thought about that.

Do you have any cheapo cpu to try first to make sure nothing crazy happens?

How would removing the bracket that keeps the CPU pressed in while you mount a heatsink make it have LESS force?
