Default A thought about better engine cooling

So I'm in the computer industry and in my spare time I build high end overclocked game machines for people (See mine below ) There's a big emphisis on cooling in this market.

Anyway, I was thinking (yes dangerous I know) has anyone thought of or tried a thermal conductive paste between the head button and the head?

In the PC world this is used between the CPU and whatever cooling device you're using to aid in the transfer of heat from the processor to your heat sink. I can tell you from first hand testing that without it you'd fry computer processors, that's how much it helps with the heat transfer. It's designed to fill all the small air pockets, scratches and imperfections between the surfaces, thereby increasing the actual surface area for the transfer.

Anyway, I was thinking that it would make the heatsink more effective at cooling the engine, thereby allowing you to run the engine leaner and make more power.

This could also apply between the engine block and mount, and between the mount and chassis.

Might have to get some cheapo engines and test this theory

Yes. I often use it on my onroad motors.

It is especially helpful on some of the older OS or other motors where the bottom of the heatsink wasn't machined but just left that same rough anodizing that's on the rest of the head.

What kind of results did you see after you started using it??

I used to do this several years ago. Didn't really see much differance in temps. It got to be a hassle to clean and re-apply everytime I worked on my engine. I belive it should actually help. More so on some engines than others, depending on mating surfaces of the heatsink and head.

Yea, watercooled Quad Core Xeon 2.13GHz stock, I run it at 3.8

That paste on Amain is probably similar and more than likely used for heatsinks on ESC's and Motors.

What paste were you using? The quality of it will definately affect the results. I've seen variations of 20C from junk crap to some of the best. That's a BIG difference in Temp (68F)

And that's on computers where 140F is conisdered dangerously hot, we're running engines in the 200-250F range so I'd think the gap could be even more in this application.

There's also the issue of "setting" the paste. You have to heat cycle it and some won't reach full potenial for 2 weeks or more.

we had a brief discussion last year.

Thermal paste between heatsink?

I don't see benefiting much from this theory. Does not mean I am not wrong.
Feel free to do some testing and get back to us

I think there is more to it than getting engine cooler so you can lean it out.
Just because you get an engine cooler does not mean it will perform the same when you lean it out. I know that's not very a technical explanation but best i could come up with. Maybe some engine guys can chime in. I bet Mr.Twister would have some input on this.

Here's a few more pictures of my "blinged" PC

But seriously, the $ I've made after people see it and want something like it more than paid for what it cost me to build it







The Stealthed DVD burner













Before the mod



The internal radiator with 3x120mm fans custom installed into the top of course











Sleeved and hid all the wiring behind the motherboard tray



This thing is HOT
