Iceland volcanic ash and my PC

[Chan Chung Hang Christopher]

>> About a year ago I had a Dell Service Tech replace the Dell PC fans ,

Is your PC holed up in a part of a desk or something? That is, besides 
it having sufficient fan power, is there room for the hot air to 
disperse and not be cycled back into the case?

I'd love to get my hands on such gear to destroy my fans. Then I will 
have an excuse to get ones with ball bearings.

I would add use a vacuum (low powered) inside the case too.
