Zalman CNPS users: Cleaning tips?

[Loki1]

I've read in various places that dust build up between the petals of the Zalman CNPS becomes a problem after a while cause it results in higher cpu temps. Is this true? Any tips on cleaning. People said they've used compressed air to blast dust out or paint brushes.

Compressed air works for me.

Just don't get too crazy with the compressed air spinning the fan. I had my tank at 50 psi and I was having fun spinning the fan and I melted the bearings in the fan.

I use a 1" natural bristle paint brush. The bristles slide easily between the cooling fins. (I've found that cheap paint brushes are not as flexible as natural bristle ones).
Good luck!
