Yup.
- Your pump draws some power, all of which will become heat
- You
may need a more powerful fan (adding one that can pull air through a radiator or heater core - removing one that moves air through your CPU heat sink)
- Your power supply is not 100% efficient. If you're using a 12VDC pump, there'll be some additional loss (heat) from your PS - and of course, from whatever additional fractional watt you needed for a more powerful fan.
- CPUs are not "ohmic" devices, so running faster, even at the same voltage, will consume more power - which becomes heat
- And, of course, if your PC now becomes quiet enough that you can leave it on at times when you used to shut it off, that constitutes additional heat.
Does any of this add up to an observable rise in ambient? Hasn't ever for me. (Leaving my big-ass monitor on can do it, though...
