| About this blog: Computers hate me. They really do. Every time I try to do something unusual like add new hardware, something is guaranteed to go wrong. I decided to start writing about my constant problems so that someone else might benefit from my experiences - or at least laugh at them! |
I've submerged a thermometer into the bong cooler reservoir, which means I can now measure its effectiveness. The thermometer cost $16 off ebay so I doubt it's that accurate, but even if its reported temp varies by a couple of degrees above or below the true temperature it proves that the bong cooler is able to chill the water in the reservoir (slightly). Current ambient temp is 32.5C (it's a hot summer night), reported water temp is 25.3C. If I add a reasonable heat load (eg a Q6600 CPU with all 4 cores working flat out) the reservoir water temperature wanders up by about 1.0C; in this case the reported CPU temperature is about 32C, although I'm not sure how accurate that is.
The probe is sitting right at the top of the water level since the cord is a little too short; eventually I hope to have one sensor at the bottom and another near the top for comparison. The pump is submersible so it draws water from the bottom (an area which is hopefully a bit cooler).
I've also made a few tweaks in the past few days and the cooler has become significantly more thirsty - requiring more frequent topups - which is a good sign that it's working.
One thing I'm concerned about is winter temperatures pulling the outdoor reservoir temperature too low. If it falls to single digits there may be condensation issues with cold water being piped into a hot PC...
UPDATE: Daytime temps... ambient 38.4C, water 27.4C (11.0C difference!), CPU 26C (idle)
