Just got my Archimedes TEC block in today and it is a thing of beauty. I will be running it with the 62mm Thermonamic TEHC1-19940, which is over-zealously and theoretically rated at something crazy like 630w Qmax @ 24v but is closer to [email protected]
in the real world...which still makes it the most powerful 62mm TEC available and a whole 72w @ 12v more powerful then the former top dog CTE 400w that I am currently running.
There are already plenty of good pictures of the block itself, but the first thing I would like to mention is how great of a job the machining was on this piece - I lap all my parts (by habit, probably not much difference with a TEC) and this was by far the flattest and easiest to lap block/heatsink/cold plate I've had the pleasure of doing. It didn't even need a real multi-stage lap...I literally spent under 5 minutes and just hit it by hand with some fine grain 1500 finishing paper before polishing it with a paper towel and a drop of 3M Perfect-it stage 1 (best polish ever BTW if you have a dark vehicle, commercial grade stuff that you can't find in stores). To compare, I usually spend close to 30 minutes total with a sheet of glass and wet paper stuck to it going from 800, 1000, then 1500 before killing myself with rubbing compound and then polish ending with a sore arm
Before (extremely flat, acceptable surface but has some machining marks):
After (spent literally FIVE MINUTES with that ~1.5"sq piece of sand paper you see and a drop of that polish...thats it!):
Will run some base tests with my current setup by Saturday night and hopefully start installing this Sunday and re-running with everything besides the block identical. Planning to do some simple hyperpi runs at 4.5ghz, 4.7ghz, and 5ghz for people with different OC'ing chips. Since my controller currently limits me to 0c cold plate which it can hold at 4.5ghz I expect the Archimedes to be the same at 4.5ghz, slightly better at 4.7ghz, and much better at 5ghz where my current block gets overloaded and starts creeping up. That should also show in nice easy to follow numbers how a TEC behaves when it starts being ran past its rating...things get nasty QUICKLY :jest:.
