OK, thanks for the info. I have some nylon washers on order, I'll give it a good look when I'm starting my build.

Hi all, I received my Aquaero 5 LT and waterblock yesterday, but the waterblock came with 3 metal screws only. Is it supposed to be mounted with these metal screws, without spacers or anything to isolate it from the PCB? The reviews I had read all mentioned plastic type screws, but that's not what was in my package. Greetz, Tom
