Special blocks for Pelts, or can you convert?

Ok, so I'm pretty new to the WC setup, but I'm already looking forward

The question is: I have a DTEK Whitewater CPU block and a Maze4 (not the Maze 4-1) GPU block. I've been reading that the whole coldplate -> tec -> block needs to have a lot of clamping pressure, does this mean that I have to get rid of my current blocks and buy ones that are specially designed for peltier elements?

Or is there a way I can "convert" my current ones?

And just out of curiosity, anyone pelt an X800 yet? Curious what size I should go for; I'm thinking an 80w unit just won't be enough.

The whitewater block will not work with pelts period because the internal design is not designed for cooling a large pelt only a smal cpu die.

It may be possible to convert a Maze 4 into a Maze 4-1 by adding the cold plate but im not 100% sure normal maze 4s have the mounting hoes for the cold plate. Oyu will have to check if your block has small 3mm threaded holes in each corner.

A 80w pelt sould be able to handle a x800 well.

Yeah, I did some more research after posting here and realized that my DTEK just cannot cut it for a pelt. I may hold off on pelting my rig until I get a chance to become more accustomed to the WC setup in general. I'm also unsure if my radiator can deal with 400+ watts of heat (80W pelt + 172W pelt + CPU + GPU)

My temps now aren't that bad, I'm just wanting more...

The main difference between the Maze 4, and Maze 4-1 is the block's base. The Maze 4 has a raised base, to accomodate the shim most GPUs have. The Maze 4-1 has a flat base so that the peltier hot side can have full-contact with the waterblock, while the coldplate has a raised base to accomodate the shim.

An 80W peltier will work fine on your X800 XT - but you won't be seeing sub-ambient temperatures with it. An 80W peltier sees it's full efficiency (~80W) when operated at 16V. Run at 12V, off of your computer's PSU, ~55W is roughly what you'll see.

A 172W peltier, in contrast, handles at about ~66W when run on 12V, and gets to it's peak of 172W when at about ~24V.
