Work In Progress

The heating issues are almost solved.  I have installed a simple radiator and pump to cool the liquid paraffin. The pump being used is a simple atman aquarium pump with a capasity of 2000 l/hr and head of 3 meters. The radiator is from a old fridge i slavged from a repair shop. 

After just circulating the hot oil under high load conditions (Call of duty 5) The temperature settled at a good 47 degress from 72 degrees without the radiator. This is quite good since ther eis a 30 degree drop in temp and the ambian temperature outside is around 32 degress. The perfomance was improved further by attaching a fan to the radiator. The new stable temperature are 40 degrees without load and 42 degrees with load

Shall upload thepictures soon once i make the reg more presentable

First Reports

The computer seems to be doing good In terms of Performance. Running Call of Duty 5 at maxr resolution without any framing. 

Since i havent put it any cooling provisions the temperature keeps rising... i havent really checked the max but i have reached around 56 degrees for the liquis.... 

The problem seems to be that although the liquid seems to be absorbing the heat from the components it is just storing it . Unless  there is a way to dump the heat to the atmosphere cooling will not happn

Hybrid Water Cooling


Keeping options open for cooling, circulating oil is working out to be much more difficult than I expected. The high viscosity of oil is making circulation quite difficult. I am thinking of cooling the oil immersed computer with water. How do I intend on doing this quite simple. The schematic explains the Basic system. The coolant is stored in a reservoir (1) . A simple aquarium pump (2) is used for circulating the coolant. A heat collector (4) is immersed in the oil (3) in which the CPU is immersed. The coolant is circulated through this collector from where the coolant absorbs the heat. The heated coolant is then passed through a radiator (5) which will radiate the heat to the atmosphere. The coolant then returns back into the reservoir
