Ära siis peltieri unusta panna, muidu ei saa saa oma vesijahutusest kuidagi rohkem kätte kui toatemperatuur. Siis on olemas ka freoon, vedel lämmastik..., a see selleks. Tegelikult on arvutituunimisega, nagu autode puhulgi - ühed värvivad korpusi ja panevad lambikesi, teised panustavad jõudlusesse. Värvipoti, sae ja pleksiklaasi ja jõululambikestega tuleb asi muidugi odavam välja, aga pedemajakaks jääb ta ikkagi. Samas tuleb ka aru saada, et kui ikka "rauda" sees pole, siis pole ka jahutada midagi ja panustatakse puhtalt välimusse. Nii on ka arvutite puhul oma pedetuunijad samamoodi nagu autode puhul

Peltier hästi lühidalt: metallplaat, millele vool sisse ja üks pool läheb külmaks, teine omakorda kuumaks. Jahedama poolega jahutame protsessorit, kuumemat poolt jahutame veega. Puhtalt veega jahutades ei saa me alla toatemperatuuri (kui just kraanivett ei kasuta pidevalt), peltieri kasutades, saame protsessorile läheneda juba pinnaga, mis on all 0 kraadi. Seega paljalt veejahutusega blokk ei sobi ekstreemsemaks "ülekellamiseks", sest bloki temperatuur on kuskil 20-25 (toatemperatuur), peltieriga varustatud plokk, aga miks mitte -20 kraadi. Oluline vahe.
Pikemalt:
Peltier devices, also known as thermoelectric (TE) modules, are small solid-state devices that function as heat pumps. A "typical" unit is a few millimeters thick by a few millimeters to a few centimeters square. It is a sandwich formed by two ceramic plates with an array of small Bismuth Telluride cubes ("couples") in between. When a DC current is applied heat is moved from one side of the device to the other - where it must be removed with a heatsink. The "cold" side is commonly used to cool an electronic device such as a microprocessor or a photodetector. If the current is reversed the device makes an excellent heater.
As with any device, TE modules work best when applied properly. They are not meant to serve as room air conditioners. They are best suited to smaller cooling applications, although they are used in applications as large as portable picnic-type coolers. They can be stacked to achieve lower temperatures, although reaching cryogenic temperatures would require great care. They are not very "efficient" and can draw amps of power. This disadvantage is more than offset by the advantages of no moving parts, no Freon refrigerant, no noise, no vibration, very small size, long life, capability of precision temperature control, etc.
