28 C is still above room temperature

maybe his mobo is reading the northbridge temperature?

(28 C * 1.8) + 32 = 82 F

if is room temperature is < 70 that is entirely reasonable

mobo temperature of 34 C = approximately 100 F

and i dont think his room is 100 F

room temperature is about 25 C typically

you Americans need to learn metric / SI :D

Hey, motherboard monitor allows you to set any sensor on the motherboard to sensor 1, sensor 2, etc. So, you could have the cpu temp as either of them. In this case, i think 33C is actually his cpu temp. Lets be honest, he would need to be retarded if his case was that hot and he was such a cooling freak. Besides, my case runs about 28C, which conicides with his "so called" cpu temp which is really his ambient inside the case

Just my 2 Cents

<< We do have CPU that run cooler;they are called "Intel P4,s" [sic] >>


I understand the tongue-in-cheek-ness :), but it is totally impossible for anything to be cooled by air to have a temperature cooler than the surrounding air.

When I saw the first pics I was like uhhhhhhh WTF is that thing? But once he got it all done and finished... DAAAAMMMMNNN thats a AWSOME job for a homemade heatsink, looks VERY proffesional even if its a MONSTER.

<< i always thought that the mobo sensor was on the chipset.... >>


my asus board has a separate chip that is actually pretty far from eveyrthing else that monitors the temp. if I hold my finger on it it changes the temperature reading :)

watercooling would have gotten just as good of results (if not better) with less work and a hell of a lot less noise! did you see that fan?!?

you're right, but read the first section on his page.

i dont think he's trying to win a nobel prize for science, he's just trying to make the biggest meanest heatsink. :D

Are you sure that fan is loud? I'd rather pay ONCE for copper than pay REPEATEDLY for electricity to run the water pump. In a year he's probably more than justified the expense.

I think his procedures sucks. Gripping something that big in a vice is just going to dissipate heat. You should cook that thing in a smelting oven, then work on it over a firebrick. I don't know what kind of acids he's tried, but copper oxide IS soluble in hydrochloric acid as well as alkali cyanides such as sodium cyanide.

well real life is different, but the important thing is it worked

MadRat, that is a 56 DB dfan. definitely VERY VERY loud. not as high pitched as a delta 60mm, but not something i would want to be around.

Not only that, the internal heat transfer probably sucks. Since the copper didn't melt together, it's held together by silver solder. I'm sure there are imperfections - and it sounds kind of strange. The thing was held together with a vise, silver solder was poured on top and you've got base? LOL

I'll garauntee that the copper is fused together. At twenty-five tons of pressure the copper plates were easily impregnated together. I can fuse two copper sheets together with much less pressure. Using silver for the base and as solder is no different than the aluminum heatsinks with a copper core, only you're using the ONE metal that conducts heat more thoroughly than copper. He probably can displace more heat without a fan than a normal heatsink with a 5400rpm fan.

Watercooling would definitely be better assuming condensation problem is properly dealt with.

Check out my water cooling engine. This is a kind of unusual setup. A typical water cooled sytem has a peltier at the CPU and external radiator with a fan tries to bring the water temp down as close to room temp as possible. This setup simply uses a copper water block. Freon 12 refrigeration unit cools the water and simply circulates it into the block. By using anti-freeze, I can go down to -15°C under 100W thermal load.


Gigantic heatsink, no matter how cute they're, they won't go below room temp.
