Large and Heavy CPU coolers??

[btbass]

I have just bought a Be Quiet Dark Rock Pro CPU Cooler.
This thing is large and heavy. It weighs 1550 grams or 3.4 lbs in English.
Having a 3.4 lb lump hanging off the motherboard can surly not be a good thing? It must put a lot of stress on the board around the processor.
What do you think????

Maybe you will soon start searching new cpu socket. When heatsink demonstrate gravitational force.


If you whant real cooling power better get water cooling or make it.

new motherboards are strong,but it can bend as time goes by. in extreme cases it can cut some connections.
if the layout is horizontial you can unscrew mobo and put something plastic under the cpu sock. to fill the gap.

The layout is vertical like most Midi towers, so it sticks out the side.
I suppose I have to be careful when moving it about and not put it down too quickly.

I have been using water cooling but have decided to go back to air cooling.
The new air cooled system is quieter than the old water cooled system.

Maybe you should fix top side of heatsink with something.

cant you return it to the shop exchanging it with a light one ?

The cooler is recommended by Custom PC for their extreme ultra pc build.
It also gets good reviews everywhere.
It comes with two fans, but I have taken one off and just using the center fan. Still keeps the processor cool.
The question is, how heavy can a cooler be before it starts to damage the motherboard????????

I guess the manufactorer of the cooler has knowledge of that. However the tension a Nowdays mobo can hold I think is up to 3kg / 20 cm2 for a long time (from my experiments!!) , since ive put things like that and even heavier in my computers.

The socket usually stucks to the motherboard with 6 screws, so the weight is divided. I dont think that you'll be having a problem , even at full weight. Maybe you'll notice after some months a light bent

Must be desktop case, not midi tower or big tower (should be horizontal).

Also heat pipes give best results when in vertical position.

Can't heat pipes compete with these heavy heatsinks on size and efficiency.
Don't know about cost.

This cooling heatsinks are full of heat pipes.

Heat pipes connecting heatsink base, with cheeler. Then adiabatic process to the job.

Heat pipes are good method to relocate heat from one place to another with passive method, I mean without fans. Fans can be added on other end to accelerate cooling and adiabatic proces inside heat pipe.

Better is vertical position for heatpipe and heatsink. ;-)
