Noctua NH-D15S screw tightness.

[BunnyKraken]

Hi,

Im installing the Noctua NH-D15S, and im a little lost how tight the screws should be. The manual says screw until they stop, does this mean all the way down until there is no more turn to turn. Or should it be like only 5-10turn when the screw is half way down ?

Can this damage the processor or motherboard, or is it safe proofed with the spring screws ?

Keep turning them until you hit the end stop- the mounting pressure is tighter than you think.

Oh okey so all the way down is basically ''until they stop'', they seem quite stiff from the start already.

Keep tightening until it no longer turns. I didn't do that on my NH-D15 and led to varying CPU temps a lot on my 9800X. My lower screw was only 2 turns on... I had it like that for a 1-1/2 years.

the screw will bottom out, it will be smooth the whole way with a little resistance but there will be a clear stop point. Don't worry about the pressure, this system is designed where the spring is actually providing the correct pressure and the screw isn't actually forcing the cooler onto the CPU like some coolers which mount to a backplate or motherboard threaded mounts.

Thanks to all, got it tighten right. 

Anyone else reading this post, just keep tightening the screws like mentioned all the way down, then it stops turning
