Weight of HSF?

[DeltaSierra]

In the article about cooling, the author notes that the maximum weight of an HSF for a T-bird should be 300 grams. But this doesn't make sense: don't most clips exert more pressure on the CPU than 300 grams?

Or, if 300 grams is the maximum weight, then what about those heavy HSFs? For example, the Glaciator weighs in at 710 grams. If my mobo lies flat (one of my systems is a desktop), am I going to crush my Tbird?

The spec of 300 grams is given by AMD. They think that going over that weight might pull of the socket. The cpu's can stand a lot more than 300 grams pressure. You can mount heavier fans of course if you use the holes surrounding the socket. By doing that you don't have to worry about the socket being pulled off.

Hope this helps you out :)

I think my glaciator crushed my athlon.....I'm not sure though....I mounted and remounted and seen one time it was crooked as hell on the top.....so while taking it off I heard a crunch sound....OMG thats not good I cleaned it off and nothing visable..but as I used a high power manifying glass I think I can see a small tiny hairline crack on the edge......so maybe heavy heatsinks are bad....but then again I did have it on crooked as hell

sometimes that crunch sound is just the HSF clip going on the plastic mobo clips. happened to me a few times and scared the hell out of me

For a 0.5 kg heatsink,

500grams * 9.81 N/kg = 4.91 N = a mere 1.1 lbf (force pounds)

AMD specs recommend a range of 12 to 24 lbf for retention mechanisms.

Cumulatively, the weight and the clip spring force won't be dangerous but when your tower casing is upright, the weight of the HSF may make it sag down (weight acting downwards, clip force acting to the sides). When moving the casing, that sagging way be aggravated and may cause chipping to your CPU.

Great! That was the kind of info I wanted to hear. That's very helpful, thank you. Now I can sleep at night!

Anyone know of any alternate way to mount the galciator, mine fell of and fried my 1.33, just got a new one from new egg? I like the way the p4 is mounted very good retention system.
