It actually cools things alot- what I should have made more clear is that the maximum oc for the e4300 with water is 3.55 at 1.63V, so it's running faster, with alot more voltage than I was giving it with the air cooling.
Despite that, i was a little surprised at how high the load temps for the e4300 were.
Another thing that is an entire other article is that I don't trust the temperature probes in the CPU or the sensors in the motherboard at all- I get different reading with every program, and the some of them are whacked! they are also whacked in different ways with each chip.
speedfan read 21C core for the e4300
Coretemp reads three degrees lower than TAT
there were other oddities too.
Temperature sensors just aren't calibrated with any care because of several different manufacturers producing the different components. I don't place much stock in temperature readings anymore- especially now that I'm on water cooling- I'm not going to go 24/7 with anything much over 1.5V so I don't have to worry.
