to clean your heatspreader and hsf you should use a lint free cloth and alcohol

Can the paste be washed off of the cloth afterwards or will they stick?

Can the cloth be used for anything else afterwards like wiping the monitor etc? Or will the particles forever remain in the fabric?

I just use a paper towel and alcohol. Works fine for me.

some microscopic particles will probably remain in the fabric. I probably wouldn't use it to clean a monitor with.

Default Re: Thermal right heatsinks.

I don't get how these heatsinks perform the way they do.

Why are the differences so significant? They all look pretty much the same to me. With heatpipes and fins.

Plus, shouldn't there be an "optimized" design? Like Zalman has round ones and Thermalright has tower ones.

Plus, why are some aluminum and some copper? Shouldn't they all be copper? Like the U120E is the best cooler, but why wouldn't they make it copper?

Like when one performs MUCH better, but the two are of the same size, all have large fins, and all uses the same number of heatpipes, what accounts for the difference in performance?

You'll actually fine a lot of the highend Aluminium coolers have a copper base, but are covered with Aluminium for protection. The fins and the rest are aluminium to keep the weight down otherwise they could damage the motherboard.

Yep.

I have a tiny 60mm Global Win socket A cooler thats made out of copper and it weighs almost as much as my aluminum Thermalright Ultra 120 Extreme. Needless to say, the extreme works much better.

I love my Thermalright Ultima-90 cools like a champ and fits in my narrow case.

So shouldn't we have figured out the "optimum" design already? Like this isn't as advanced as the processor.

Why do some use (Zalman) copper and some big aluminum ones? Also, what justifies the differences in performance between two nearly identical heatsinks? Like two aluminum tower HS?

I thought this stuff is supposed to be really simple, what's with all of the different designs?

Apparently it isn't simple, and I've never heard anyone say that it was.

Understanding the millions of different ways that air can flow through a heat sink in order to remove heat from the fins doesn't sound very easy to me.

As far as copper vs aluminum, its a matter of weight vs heat transfer. Copper transfers heat better but is significantly heavier. Designers have to find a balance between the two. Right now, it seems like all of the top of the line coolers are made from aluminum. They can make larger heatsinks with more fins using aluminum, and this works far better than a smaller copper cooler (more overall surface area for the heat to transfer from).

The reason we still have some copper designs is because of size limitations as well as costs. A thermalright ultra 120 will not fit in all cases, and neither will most large tower heatsinks. A smaller heatsink can be made out of copper without weighing too much, plus its far less complex so it can be made more cheaply.

Designing a "better" cooler is not a simple thing at all. Though I think we're nearing the limits of air cooling unless new materials or fan designs are used.
