As usual, I have come up with a case design, but, since im not a mechanical engineer, im stuck trying to figure out whether the heat sinks will be good enough.
Basically, the case is a 360mm cube with a 80mm deep heatsink on each side, being cooled by two rows of 3 80mm (nexus) fans. The first idea was to use 120s on each side, but the resultant width (450mm cube) is a little bit big for my taste.
Ok:
The total area of the heatsink surface would be about 8.16m^2
With total air volume of about 0.02074m^3
Using some rough calcs, I get a thermal resistance of 0.186 deg/W.
Using Rth = Tr/P
I get a temp rise of 56 deg for a system dissipating 300W heat.
This is assuming only convection cooling, so how do I find the temp difference for air assisted cooling?
Basically, I’m trying to see if the case has enough cooling power to cool a cold water loop inside a totally (air) sealed case (with internal fans). Obviously this means the power dissipation is up to around 1500+W taking the 4 226W pelts into account.
Any ideas?
I realize this is hardly a normal quiet system, but I’m just interested to see if below ambient cooling can be done whilst keeping noise low and the people here are generally knowledgeable in such matters.
