Galvanic corrosion due to dissimilar metals contacting each other is not a problem here, and actually never has been in these scenarios. Science has known about "galvanic corrosion"
for nearly 300 years - though the creation of corrosion with contacting dissimilar metals has been observed for 100s, perhaps 1000s of years longer.
My point is, CPU/IHS makers, heatsink makers, and TIM makers are fully aware of the effects of contacting dissimilar metals too. They ensure (1) there is no electrolyte present as noted by the Count. But also necessary for the creation of galvanic corrosion is for there to be an electrical contact - that is no or super low electrical resistance between the contacting surfaces. So, (2) IHS and heatsink makers apply a super thin, electrically insulating resin (or something similar - often trade secrets!) coating on those surfaces. And quality TIM makers encapsulate the metal molecules in their patented TIMs with similar (and often secret/trademarked/copyrighted) insulating materials.
Yes, these coatings also introduce some heat insulating side effects - but designing and manufacturing these products to make the perfect balance between conducting heat and insulating the flow of electrons is what separates the quality from the junk products.
BTW, speaking of water loops in computer cooling systems, much thanks goes to the NASCAR and Formula 1 racing industries. They have come up with coolant formulas that provide maximum cooling effects while protecting the thin aluminum walls of their lightweight radiators from the corrosive effects of pure distilled or deionized water.
