red_dragon Posted March 15, 2004 Share Posted March 15, 2004 I've been reading various posts in various forums and I'm kinda confused. Does it or does it not help to have copper heatspreaders on my ram? Some people say it keeps the ram hotter sometimes, can that be true? Thanks!

pershoot Posted March 16, 2004 Share Posted March 16, 2004 i dont really think its needed to tell you the truth. they may actually be suffocating within the heatspreaders at times, ha. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted March 19, 2004 Corsair Employees Share Posted March 19, 2004 Heat spreaders will move the heat away from the IC's and into the heat spreader. Air flow is the critical component of cooling with heat spreaders. The cooling is there, just minimal. Link to comment Share on other sites More sharing options...

But, the way they come out of the box is probably not optimal to ahieve a difference, and actually can and may be counterproductive at times.

tenax Posted March 20, 2004 Share Posted March 20, 2004 i agree..hard pressed to see how heat spreaders allow any airflow to speak of...so they better dissipate some heat..pretty hard to get those suckers off my corsair pro:) Link to comment Share on other sites More sharing options...
stev Posted March 25, 2004 Share Posted March 25, 2004 I'll agree with RAMGUY, you 'll need airflow of 40 or more CFM to make it really pay off. Stev Link to comment Share on other sites More sharing options...
Clevor Posted April 2, 2004 Share Posted April 2, 2004 I also think the heatspreaders are not designed properly. Some of the copper ones from other manufacturers have a 2-3 mm gap at the top where the halves meet. No way air will flow into such a narrow gap. Best bet is to get the air to flow smoothly over the outer plane of the heatsink. What you want is the ovalized shape of an airplane wing here, very similar to Corsair's aluminum spreaders. Last I heard, NASCAR forged cranks had this 'airplane wing' leading edge, to reduce oil slinging at high rpm with the crank spinning. As far as I know, only the aftermarket Thermaltake heat spreaders have this profile when installed, next to Corsair's. Maybe it won't make a big diff, but it helps.
