Summer project: Watercooling a computer so it is a quiet as possible.
I have a computer case where the ambient air temperature is around 37’C and the room temperature is around 20’C.
I will be cooling two processors rated at 54.6W by piping water over them serially to a radiator which can dissipate upto 790kcal/hour providing there is an airflow of 100 cubic feet per minute.
This is quite easy to achieve, but that level of airflow creates about 60dB.
The plan is to use an ‘over-rated’ system and then have a fan powered at a lower voltage which should be quieter. It is straightforward to run the fan at 7v instead of 12v.
I have browsed around I have a pump which runs at 1200l/h. I will be using tubing with a diameter of 1/2inch.
My question is:
I appreciate it’s a little vague, just ask if you need more information :)

My question is:
- Is one radiator going to be enough to keep the processors below 45’C?
- If a 12v fan makes 60dB moving 100cfm of air, what will happen when I run it at 7 or even 5v?
