Geez, I must have completely misread this. For some reason, I missed the word "block."
The waterblock is already an infrared source of light. Just a very, very poor one - it's not at a high enough temperature to emit much IR radiation. Also, aluminum and copper don't have anywhere near the emissivity of tungsten, steel, or compounds like that.
The only way to make a waterblock, regardless of what it's made of, emit a significant amount of IR radiation - that is, enough that you could feel it by holding your hand above it* - is by operating your CPU at a temperature into the hundreds or thousands of degrees.
Fry: "Fahrenheit or Celsius?"
Old Man: "First one, then th' other."
/Futurama joke that amuses me far too much.

*If the block is very warm, you could probably feel heat coming from it via convection through the air. Your senses aren't good enough to feel radiation from anything that cold, and even if they were, they'd be drowned out by the heat coming off via convection.
