attaching fan to rad???

Okay maybe I'm stupid, but I can't seem to understand how you're supposed to screw the fans into the rads... I have a ThermoChill PA120.2 and 2 Antec Tricools... you can't screw them straight in because the other side of the fan casing blocks your screw driver. So, unless you have a tiny miniature screwdriver that fits between the 2 sides of a fan, I dunno what to do!!

I apologize for my stupidity...

Heh, I use to wonder the same thing before I began water cooling. You just have to get a longer screw that goes through the fan and into the radiator. Make sure the screw isn't too long or else it will puncture the radiator fins possibly resulting in a leak.

Here are some screws for your Thermochill:

If you have a home improvement store they're just #6 x 1 1/4 long sheet metal screws, assuming you're using a standard 1" thick fan.

Or if you have a threaded rad you can use M3 or M4 screws (usually the latter I think) and not damage the threads . Thats what I generally do with Black Ice, Primochill, and other radiators. On my heater core of course, I use long 6-32 screws.

My advice was specific to the OP who has a thermochill, I think I used M6s in my BIX III, but i could be wrong
