Okay, I put a thermoelectric (TEC) slab between my CPU and a cheap, one-fan, pre-built water cooler. It melted the pump, which was mounted directly over the CPU. It didn't melt as in "flows down to the floor", but it was visibly distorted and the rotor made noise but wouldn't spin.
So I built my own custom water cooler, and I put a 3x120mm radiator in the loop—BEFORE the hot water gets to the pump.
I also bought an asskick pump, since the little one obviously wasn't flowing enough water over the hot side of the Peltier to keep the gizmo from melting.
You may not have this problem, even if you cool thermoelectrically. But I use a 24v, 60mm 420-watt industrial TEC (It has its very own PSU, which also drives the pump). My goal is to freeze the processor solid (below 0º C) while running prime95. Why? For the only good reason to do anything at all: because I want to.
It may not be possible, but grownups say that about everything fun. I'm going to do it anyway.
So far, though I've only run the thing at 12v because I'm scared it will shoot sparks like the Enterprise control panels when the Klignons attack or something. I'm going to wait until I can afford to upgrade my MB, so I have a spare of everything when it blows up in my face. I have a history of unwise experiments which did that. In fact, I pulled the Peltier out altogether until I have spare components to destroy.
I know that instead, I could just throttle the Peltier back and slow down the clock, but that defeats the fun of being a speed freq. My main concern is that peltiers put out twice as many watts of heat than they suck up on the cold side. Plus, when my grad school fall semester living expense $$ arrives, I'm going to buy a 220-watt AMD 9590, which runs so hot that AMD sells it with an AMD water cooler. Add another 420 watts at 24 v, and I'm wondering if it will overwhelm even MY cooler. I use 1/2" tubing, and am prepared to add another pump and radiator. Even two or three more, if necessary. (I do everything with excessive intensity, otherwise it's not worth doing. "Too much" is NEVER enough!)
My question is:
What is the max heat in watts that I can expect that setup to dissipate?
Also, do you think I'll need a second radiator? There are probably equations about it somewhere, but I'm too lazy too look them up.
