Koolance Rad Fan Mounting Screws

post #1 of 7
Thread Starter 
I came across these neat little screws for radiator fan mounting but I have the H220 which is threaded for #6-32 which is M3.5 but these Koolance screws are M4 thread. Will it still work? Or will it ruin the threads if I try to use them.

You'll need to tap the radiator holes to M4. You can buy the tap for probably $5-$6 from any hardware store. You could use it w/ a drill if you are very very careful. Otherwise you'd need to buy a handle for the tap which will be around $10. IMO all modders should have a good tap anyways. I've done this to almost all of my radiators that I have used in recent years in order to use those Koolance mounting screws.

This.

Without tapping, the M4 screws will either not go in at all or will cross thread and ruin the threads on either the screws or the radiator. Tapping the radiator is definitely the way to go

I bought a tap and die set from the hardware store down the street for about $30, which included taps and dies starting at 4-40 going up to 10-32 and the tap handle and die wrench. It was worth every penny

Will tapping the screw holes have any effect on the warranty?

You shouldn't ever need to claim warranty on a radiator anyways. Almost every time a radiator leaks is due to people using screws that are too long when mounting fans. But yes you will likely lose warranty.

Well it's the H220 and I have already RMA'd it once haha.

Good point. On an AIO tapping the rad may not be a great idea.
