Intel Core i7 CPU Water Block Roundup October 2009

Cooling/Water Cooling by leeghoofd @ 2009-10-18

Here we are again, with some brand new water blocks to cool your Nehalem or Lynnfield monster CPU. We got some strong contenders this time, which will give the blocks, that we already tested, a serious run for their money. In total 7 new blocks delivered to us thanks to Aquatuning. We compare performance to 6 blocks we previously tested. Find out which one cools your CPU the best!

Phobya water block

Phobya waterblock

Phobya was a pretty unknown brand to me. Aquatuning is warranting its distribution to the European masses. Their first block, being released in November 2008, carries the same name as the company. In fact Phobya is not a company but a union of several ones. This to allow each participant has its own saying in the development and production process.

When I received the box I thought it was empty... This block absolutely is the absolute featherweight amongst these Nehalem blocks.

Clear IN and OUT markings on the top will ensure proper hook up in your loop. If you mess up, then you must be partly blind. Outside looks are futuristic, yet kept very basic without too much rif raf.

The bottom copper plate is extremely thin (reminding me of the Corsair H50 bottom plate) I really wonder how it could ensure proper conductivity between the microscopic small pin structure and the fluid passing by. If you look closely you can see the copper being bend by the screws.

The inside is less dull then the outside. A super crafted dispenser plate with micro nozzles and channels directs the cooling fluid in and out of the block. On a sidenote : don't dissemble the block for fun, took me ages to get the o-ring back into position.

Hmmm without sounding too repetitive, yes the same stuff here; screw, springs, washers and nuts and one tube of thermal paste included in the package...

Last piccie of the Phobya block completely mounted and ready to rock...

Just had to sign up just to post this comment.

Thank you!

Must have been hard work benching so many blocks... and doing them all again just due to change of thermal paste. Thorough to say the least...

Though I am new to watercooling this is the only article I have found that tests this many waterblocks. This will sure help me in buying the right block for me.

Are there any other sources available like this?

None the less. Just felt like after all that hard work you deserved at least one thank you .

And I hope that you will expand this article over time so that it could be a big buyers guide almost... Covering as many waterblocks with real tested data as possible? Or does this exist already? Would be a major way for madshrimps to become even more unique?

hi there, the author and tester Leeghoofd definitely deserves some praise for his hard work I agree
I don't know his exact plans when it comes to water blocks as he's learning along the way, but I would not rule out a standardized test setup on which to test a multitude of blocks.

For reference, here's another trustworthy source with some quality blocks compared

Thx Seth for the nice comment, I try to keep the roundups as simple as possible. The link from Jmke is the expert style, with flow charts and stuff... that's for the real die hards. Note also that they test with dual and triple pumps to get really the last degree out of the blocks. I prefer to stick to one popular pump to keep things understandable... and a sort of more european setup...

Thx for reading sir !

Well i'll try to read closer who the author is next time .

Excellent round-up, thank you very much.

Here's a suggestion for a test-rig, ready to use and manufactured by some experts: the CoolerMaster Testbench

Thanks for the nice comment
