Is that CPU cooler fan pulling air through the heatsink then?

Is that CPU cooler fan pulling air through the heatsink then?

I guess it's similar to the Scan review system here (though this has push and pull):

Pulling gives maximum clearance for memory heat spreaders and doesn't make any difference to cooling, save that dust will collect on the fins rather than fan blades.

I think Kalniel has answered this better than I could.

The beauty about the cooler being so pronounced and of course the cable management being so tidy, is that I can get a furniture brush hoover attachment near to the cooler and suck away residual dust once a week and keep it all nice and clean and cool.

If you're going to do that, then make sure you disable or unplug all fans first.

If you manually spin a fans blades you are basically turning the motor into a generator and the amount of air a vacum cleaner sucks in will spin a fan far faster than it normally runs at.
If that fan is pluged in then you can end up feeding some quite high voltages back into anything the fan is pluged into.

I've learnt that the hard way after burning out a motherboard fan header, luckly a resistor burnt out before anything major seemed to be damaged.

And possibly destroy the fan; stop them from turning at all where possible.

Thanks for the tips. Never thought of that.
