Lol, too true about them being useless. My CPU isn't even overclocked anymore....

The cost of shipping a Fuzion from you to me with import taxes is definitely not worth it. The nozzles do seem like a cheap necessity.

Yeah, cutting costs does lead to compromises, but I don't think many of them are awful. The water block side is the hardest thing to do cheaply, I don't think I have a good enough plan for than yet. At the moment its a flat sheet of copper, I'm planning on adding fins, but a milled block would be miles better.

milled block heh.. Watch out you'll end up like me saving for a milling machine. When i get mine going i could always mill you something. How about a nice shiny copper goldfish ?

it would be interesting to know how much of a difference there would be between a fat sheet and a milled block since the surface area is already large.

i got a few ideas on condensation management that i want to test out when i get my mill. Im also sure i can make a better waterblock than the fuzion.

im mainly writing this cause it's my 500th post

I really should spend my money on things that actually make my PC faster instead of TEC cooling. lol

A milled chiller. Though hes taking his time testing it.

This is true, the surface area of my 10 TEC flat copper plate probably isn't much different to the milled block in the link for 3 TECs. However I think mine would suffer badly form laminar flow.

yeah i saw that when martin was making it .. it was well made but its not the best design. If id made it i wouldn't complain though. i haven't read it all yet but 3x 62 watt tec's .. yeah right

i agree with you on the laminar flow issue it could be a real killer .. but that can be managed by making at water channel very small to keep the velocity high.. (really wide and VERY narrow )

im glad you hammered this guy .. when i read it i just about feel off my seat !!

Did you factor the fact that it can take 350W of energy to change 1C in h2o?
That doesn't actually make any sense. 350W for how long to change what volume of water?

hay if you need some back up on stuff like that i'd be more that happy to try to make people understand basic stuff.


this is a classic question ...
" I'm still having trouble understanding how he got to move 100w of heat with 63 w pelts."

um its not hard to move alot of energy with out much input power .. ie ... air cooled CPU you put in a 3 watt fan and you can cool 200watt load ... or even better .. no fan and a big passive air cooler !!! do the maths on that efficiency !!

Yeah, it can be difficult.

There are some very knowledgeable and experienced people on xtremesystems but being popular there are also a lot of people that just blindly repeat what they hear from the more respected members.

Unfortunately this means that you cant be very creative or try anything new without an army of people flatly saying "That wont work." even if you have already tried it.

This is exactly why I posted my chiller stuff here, I feel free to come up with far fetched ideas and have a sensible discussion about them.

Maybe this forum doesn't have quite as many people that have experience with peltiers, but the ones that do know what they are didn't use them just because x, y or z told them to buy those exact components.

i find this forum to be a strange one .. it's the only one that, as you said DONT have a bunch of people that dont know what there talking about claiming to know everything

it's very refreshing being here

im gonna post in that link now

boo i dont have the rights to post yet
