432583 2006-02-21 18:35:00 While looking around for a cpu cooler for my pc (current heatsink has noisy fan and I want to replace both anyway) I have noticed that some of them can be quite heavy (the Thermalright XP 90C is 690g without a fan). I am wondering, does this excessive weight cause issues with a mobo (as far as flex/twist)? Can it actually screw a mobo after a length of time having this much weight hanging off it? Myth (110)
432584 2006-02-21 19:13:00 Lots of people use them and have no problems. The cheaper/flimsier your case, the more likelihood there is of problems. You will have to take care when manouvering your box though, preferrably hold the computer on it's side (so it is sitting ON the motherboard, not hanging OFF).

I would HIGHLY recommend removal of heatsink before sending in the post or anything similar.

You have to change the retaining frame.

432586 2006-02-21 21:06:00 there is a maxium weight limit for cpu's, have a look on the cpu manafactures web site.

a lot of big heatsinks, exsecially cooper ones, go over the weight limits. this can result in cracked cpu's exspecially if you transport your case around a lot (go to lans etc). just be carefull with it if you have a heavy heatsink.

432587 2006-02-22 02:18:00 I often worry about this myself, in particular some of the all copper unit, like the Zalman CNPS7700. It's heavy enough to knock someone unconscious.

I do like the new Zalman CNPS9500, which is large but relatively light compared to some other models.
