Peltier coolers are not a good idea for daily use.
Stuff like the thread you linked are way too common, and if a peltier shorts or a diode cracks, it doesn't cool and becomes a conductor, which is a heater of however much power it can draw off the PSU.
BTDT.
I got a free Maximus IV based computer from work because the idiot who built it used a peltier cooler, and it failed.
Luckily, the PSU he used only had about 50W of headroom, so it crashed repeatedly instead of catching on fire.
If he'd built it like I do, it would have had a 1000W PSU, and looked like the one in the link, probably.
I got to do a great demo of overclocking and cooling out of that fiasco; I put a copper standard heatsink in a bath of LN2, in a custom tank I built around it.
Then I overclocked the Q6600 to 4.9GHz, while the ln2 boiled happily.
I learned a valuable lesson that day, tho; pouring Liquid helium into LN2 is like pouring water on a stove; it explodes and goes everywhere.
I thought "cold is cold", right?
Yeah; No.
Don't do that; it ruins your cred, lol.
I'm thinking of doing a water cooled system, and putting a peltier in the tank, with a thermal
fuse to ensure against any disasters. (Peltier cooling happens separately, outside the tank, obviously)
Thoughts?
