I can mount this: http://www.chilledpc.co.uk/shop/prod...roducts_id=467 on my San Ace 9G-H1011 and then mount it directly to the MegaShadow but I'm worried about the silicon melting when using the CPU 100%.

What do you guys think is the operating temperature of silicon fan gaskets like this one?

Raiden911

I doubt that silicon will melt because the heat going up the sink will be dissipated by the fans through the case.

FYI, the silicon melting point is 1410 º C (2577 °F)

Oh, so the heatsink itself isn't that hot compared to what HWMonitor shows?

And I don't know but the operating temperature mentioned in this site: http://www.acoustiproducts.com/en/fan_gaskets.asp is -20 to 70C.

im thinking that if the gasket itself is hitting 70*c then you have a pretty big problem as the base of the HS is most likely at ~90-100*C

Oh ok. So as long as my temps are 80C max (Overclocked), I shouldn't worry about the silicone?

sinaugustus

yea i think you will be fine, also you have to remember this product is going to improve the efficiency of the HS+F

From what im reading if its a soft silicon washer the melting point is MUCH lower.
+ or - 70C. I might double check before I mounted that on to my overlocked heatsink.

Yeah

So with the fansis gasket, is it of soft silcon material?

quaddragon

That's a good question. No idea /shrug. You can pretty much bet the washers to mount between the gasket are gonna be a soft silicon.

Silicon and Silicone are very different things (though silicone has silicon in it).

Anyway, if you have a fan on your heatsink, it's never going to get to 70C.

I'm testing a new OC on my i7 right now. CPU temp is in the mid-80s C, heatsink can't be warmer than 45-50C, and this is a near perfect mounting between two lapped surfaces with good thermal compound.
