Motherboard flexing with intel sotock cooler.

post #1 of 16
Thread Starter 
Hey, my motherboard seems to flex a bit with the Intel stock cooler installed, it's just a little curved without the cooler, but you can really notice it after the cooler is fixed in. It works fine when flexed, ran it for a few hrs, outside the case though.

This never happened to me before, and even if it did, I didn't notice it. I noticed this one cus I was drooling all over it!

Some pics:

I have a Zalman 9500 on my other PC, and will use that when I'm ready to put this together, was just using the stock cooler to run some tests (never used any stock cooler, well except for my P3 slot processor), out of the box, I would have never noticed this if I had installed it in the case immediately.

DO you think I should try and return the mobo? got it from a store.
And what about the slight curving without the cooler.

Thanks.

Update:Just got off the phone with the store dude, he says its normal... Just sent him these pics.

if its curved without the cooler on it ...send it back

the stock HSF is super crap i remember putting one on & the pins were total ***** ...the board will flex a little when applying this abortion of a cooler but those pics were scary

& with that lovely board u have i just wouldn't risk it

RMA the board (if curved)& buy another cooler while u wait

that's what i would do.....

If you see the first 2 pics, you can see it just a little bit curved, is that normal, It seems OK.

Thanks.!

Well I was talking about with it but honestly they really shouldnt be flexing much if at all without it. I mean you never know it could be a defected one somehow that could have slipped through so I would get that resolved sooner rather than later

it will flex without the cooler but once the cooler is attached it should be straight...

tell them when u got it out of the box it had a slight curve in it & u did not want to risk applying the cooler in case it had a crack in it

& they will replace it......

There is some flex in most mainboards and the intel cooler is quite weighty. It will cause the board to bend like that along with the weight of the heatpipe arrangment. As long as there are no visible signs of any cracking anywhere on the board it should be ok to use.

The increased flex when the cooler is fixed in is due to the 4 restraining pins being heavily sprung to provide enough force to keep the cooler in constant contact with the cpu. They pull against the mainboard at 4 fixed points so until it is securely fitted on the case stand offs the board will flex under their force too. Most decent quality mainboards have a rigid metal backplate behind the cpu socket to transfer and spread out some of this loading to prevent this occuring.

Once mounted properly on the case stand offs it will be flat.
This is what someone at the Asus's VIP forums had to say... what do you think?
