Screws?

Ok so I just got my radiator, my fans , and some othe rlittle extra stuff..

My plan is to cut 3 holes on the top of the case for the fans.

The screws that came with the radiator can hold the fan and screw into the radiator but not very far, and then with having the case in between also it will be tight. Is it ok for their not to be much thread screwed into the radiator? as long as it is holding? or should I get longer screws, cuz Im not sure which type...

I know it will screw in just not that far. is that ok??? is that how its meant to be???

What radiator do ya have? Then I could tell you what screw you'll need.

Swiftech MCR320-QP-K Triple 120mm Radiator

thats the one... came with some screws and stuff

Get some M3.5 screws, avaliable that your local hardware store and get whatever length that suits you. But if you can't find those, you'll need a 6/32 tap and some 6/36 screws.
