CPU Fan touching motherboard heatsink?

I have a z68 Exreme4 Gen3 and just installed the NZXT cpu heatsink and fans. I was wondering how hot the integrated motherboard heatsinks get as one of the fans is touching it. In other words, is this okay or will the temps get high enough to melt the plastic?

I would imagine it will be fine but if you are worried you could always file down the edge of the heatsink a little

i wouldn't worry about the temperature, worry about the fan stopping due to the contact

The rotating blades make no contact. It's the outer rim that touches.

That (removable) decorative cover of the heatsink will not get so hot. And from what I can tell the plastic of the fan normally touches the fins of the CPU heatsink, so I guess it can handle a decent temperature. No need to worry.

You wont have a problem with it melting the plastic at worst it may make the fan a little nosier. If it bothers you I would get a few zip ties and run them through the mounting holes in the fan to mount the fan to the heat-sink. That would allow you to raise it a hair.

Some of those decrative pieces on the motherboard heatsink can slide off. On my S775 Foxconn x38 board I had to slide half of it off because my 212+ wouldn't fit.

It won't get hot enough to melt plastic. I agree that noise is mostly. Warping of the fan shroud so the fan blades hit is also possible if enough pressure is applied. That's one thing I like about the 212, the fans slide into position so if you need a bit more room you can just slide it up. Or see if that heatsink cover will slide off.

Bingo! A little screw takes that cover right off. Thankyou.
