Pointless because the water loop is vastly more efficient.


Thermaltake did make a block like that though... let me dig it up...

My idea is similar to this Thermaltake's product.

Has anyone had any experience with this UFO thing?

Before i got my Supreme LT for a steal i was all set for sealing an old smallish heatsink. That would have worked similarly to a block (except that it was alu..). This is just pointless.

I meant as in a water block. I guess I should have clarified...

I'm pretty sure they would still make it and other companies would have picked up in the idea if it worked.

Not anything like that. I said "traditional waterblock w/HSF on top" Not a "HS integrated into a waterblock"
HSF=heat-sink fan.

That's what radiators are for. You shouldn't need any extra cooling if you have enough radiator for the loop. And if you do have enough radiator for your loop, you shouldn't need the extra cooling, on top of that, it probably would be detrimental rather than provide actual extra cooling. It would be taking air from inside the case and trying to cool the HSF on top, whereas a typical watercooling setup, when done properly, tries to intake fresh air over the radiator.


As for the thermaltake block... Leave it to thermaltake to do something like that... I am curious how the extra step of the liquid evap process inside the heatpipes leading to increased cooling like they claim. Maybe increased cooling over air cooling, traditional watercooling, me thinks not.

The basic principal you are trying to go against is that you are using the same amount of energy to remove heat from the system but you are adding in thermal transfer resistance by trying to watercool a HSF rather than watercool a waterblock. The bottom line is the increased surface area of the HSF won't lead to lower temps, water runs through a block fast enough that it never reaches it's heat capacity, not even close really, so you don't need to increase the rate of thermal transfer. Not that you could because in the end it's all limited by the amount of surface contact and thermal transfer you have between the bottom of the HSF or the waterblock and the IHS of the CPU.

Rather digged out this thread than starting a new one on this topic.

Lets say its not so effective to cool the surface area of the fins with water because its designed for aircooling but in principle :

1st

If you have a pure copper block and a heatpipeblock the heatpipe will transfer much more energy to the "cold" end of the heatpipe and faster then solid copper would do. thats why heatpipes are used in aircooling and in graphic cards too sometimes (Vapor Chamber heatsinks) .

2nd

The most effective way of cooling is phase change cooling which heatpipes do use or lets say compressors. Nuclear reactors are cooled with phase change cooling (boiling water reactor).

so if you have a block (heatsink) with heatpipes in the bottom like with a regular air cooler and then add a heatsink like the bottom plate to the top of the heatpipe this should deliver a better result then the stock base plate. Grahpics card already use Vapor Chamber heatsinks which work in a similar way so it would just make sense to use a heatpipe or vapor chamber for cpu cooling also...

so you just would need to somehow take the fins off the top of the heatpipe and add a heatsink to it or build your own one...
