The efficiency of a water-cooled system depends on how cold you can get
the water. It seems like the temperature of your room is the coolest
the water can get. Air near the floor of the room is usually the
coolest in the room. The most innovative solution I heard of with a
water-cooled system was running the hose outside and underground
(actually a pretty deep hole) to get the water cooler. Alternative,
maybe put a peltier cooler on it (outside the case on the cooler
portion) to chill the water.
Just speculating...;-)

After several years of hot summers and no air conditioning, I decided to try
a liquid cooled system on my PC this year. So far, I have not been overly
impressed. The reported CPU temperature (speedfan, Asus AI Suite, CPU
Thermometer) averages about 15 degrees C over the ambient air temp. This is
not much better than the Noctua air cooled system I was using.
With an ambient temperature of 18 degrees C, the idle CPU temp is about
32-35 degrees C (varies for the 4 cores). At 100% usage, the CPU temp rises
to about 73 degrees C.
My worry is that when the room temperature reaches 35 degrees C, the CPU
will be running 80 degrees C at 100% usage. I don't plan on running it at
this extreme for extended periods, I just thought water cooling would at
least get the idle temps closer to ambient temps and keep the 100% usage
temps a little lower.
I used Arctic Silver Ceramique on this build as this was what the
manufacturer of the CPU block recommended. I have used Arctic Silver 5 in
the past. The current instruction say to lay a line of the thermal compound
across the CPU. Would these temperatures indicate an incorrect application
of the thermal compound? Any other suggestions or am I just expecting too
much.
Thanks for your insight.
