Making a waterblock from a heatsink?

[JoeCrappa]

i read at www.overclock-watercool.com that making a heatsink into a watersink performs 5-10 percent better than the leading waterblock. i quote:

"I have to credit Joe Citarella of overclockers.com for this idea, because after reading his article here, and doing my best to create an innovative design in waterblocks, it appears that a heatsink designed for air-cooling is about 5-10 percent more efficient in a watercooled environment than the best designed waterblock. "
what do you guys think?

Some may have better performance some may not.

i can image it would just if you used say one of the best Fined Heatsinks around all copper and then stuck a waterjacket on it then yes i guess it would be great :D

Check out the block I made from my orb. http://daocplace.com/~bender/waterside.jpg My next version will be built from a dragon orb. I will have the top fan still in place but I'll have the copper cap underneeth. It will be a kind of cross between air and water.

I have made 2 waterblocks out of heatsinks. (Neither were really original designs)

The first one I made from a 486 heatsink and a PVC endcap. I don't use it right now b/c I didn't want to epoxy it to a CPU, but if I burn the calories to build a hold down it might be pretty decent.

The second was built from a Dragon Orb and it uses air and water to cool my sig system to a max 36C under 24/7 Folding.

Good luck, YOU CAN DO IT!

It all depends on the setup, but using old heatsinks as waterblocks is a good, effiecient, cheap way of selling waterblocks.

I epoxied some plexi sides and a top around an old heatsink from a dead Cyrix box I have here. It was a bit beefier than a regular 486 HS but not too much. Anyway, it performs outrageously well- Keeps a Celeron 995 at no more than 35C or so, full load. All for the cost of a tube of J-B Weld.:)

It's a bit sketchy, as no matter what you do you'll have a big seam going on, and since it's homemade there's always the chance it could break, but it was a good project. I bet welding a top on would be pretty failsafe; I wouldn't use plastic walls if I had it to do over again. After a month or so I went to clean it, and as soon as air hit the inside of the block the plastic became all cloudy and gross. Still works tho.:D
