Big Heavy Heatsinks, why use the clips?

[Kuasimodem]

I have noticed that heatsinks are getting heavier and heavier, but they all clip to the socket. This causes extra stress on both the socket tabs (some people have broken theirs) and on the soldered connections from the socket to the PC board.

Why can't someone come out with an aircooler that connects directly to the motherboard like this waterblock? (http://www.dangerden.com/images/MAZE21/maze21_front_large.gif) It would take all the stress off the socket, and every motherboard that I have looked at has the four holes around the socket that this waterblock uses.

I agree. Much like the recently discussed and reviewed Swiftech MC462. I recently began using a HSF assembly with 3-clasp connections on each side due to the socket nubs or extensions snapping off under the stress on single clasp connectors. But ultimately I think the innovation you're referring to makes great sense, at least for the really large heatsinks. And interestingly mobo makers are thinking the same well, as many boards (e.g, Iwill) have the holes for such sinks alreadindy drilled out in their boards.

A mobo mounted, air cooled sink is doing great wonders for cooling.

Thanks for the link Bovon, but that $80 price tag would pay for over half of the water cooling system I'm building.

I like the cooler, and the specs are outstanding, even with a normal 80mm fan on it.

I wonder if I could build something similar. solid copper with fins instead of pins, cut the fins with a mill in my drill press.

Gotta think on that one...

Artic Silver Thermal Adhesive works well for holding "bricks" the CPUs!

Randy48,

You still have to factor in all that weight hanging on the processor and socket with a vertically mounted motherboard.

If you bond the cooler to the processor die (which is tiny on the T-birds) you stress the die, the processor pins, and the socket's solder connections to the motherboard.

I like the Swiftech MC462, but two things are keeping me from ordering one.

The price, which isn't bad compared to the cost of a water cooling system, is the lesser of two factors.
The biggie for me is the noise factor, I have my computer in the living room of my house, and the 46db noise level would drown out my TV. My present system with 7 cooling fans is loud enough, I don't need a Delta "Screamer" to add to it.

Kuasimodem, I've got an extra large Alpha on my SlotA glued to the die and cache chips...no problem! The little bit of noise you're talking about is nothing http://www.sysopt.com/forum/wink.gif I've got two OC machines under my drafting table/desk with a total of 10-90mm fans, 4-120mm fans, plus PSU, CPU, slot, and bay coolers between them...and then there's my KEG http://www.sysopt.com/forum/wink.gif dual power supplies, one running the machine with 4-90mm, and one running a 12 volt radiator fan out of a Nissan drawing air up and out.............Sure, I sure HUH??? alot http://www.sysopt.com/forum/wink.gif
