I recently ordered the normal flow CPU cooler from GeminiCool.

I dont have good machining tools, so my original water block wasn't a good fit, and I didn't want to wait a few more months to have access to machines to make a new version, so I ordered this block.

I really like it, it is a beautiful cooler, but my motherboard (Shuttle AK-11 v2.2) uses 1/4" mounting holes, and the cooler came with AMD's standard 1/8" holes.

I called Peter at GeminiCool and he sent me a set of hardware to allow this block to fit. He sent it at no cost. He also took the time to explain some things in detail.

If you can't build your own block, I really recommend these blocks. They are very concerned about quality, and that everything will work first time without fuss.

Here is their website:

There is also a review of this block around overclockers.com: "The Big Blocks on the Block" John "Hoot" Hill - 3/13/02

Neither the review nor gemini.com mentions the mounting hole requirements, it is assumed your motherboard uses 1/8" according to AMD standards (which may be changing or dropped soon) so please be aware of your motherboard mouting hole size.

Good Luck,
Wow, no kidding. I order two blocks today, and Peter and I talked for about half and hour. He went over everything in detail about the fittings, the leak testing, the history of the company, ... everything. It is a great joy to see people like Peter selling hardware.
For those considering ordering Gemini products, I can also attest to Peter's passion and openness. We talked about the system for at least an hour and a half and when I offered to buy directly form him, he refered me to a distributor I had done business with before in order to promote distribution and further sales.

The theory and manufacturing process information was fascinating. I just hope Peter still has time to make products. :D
