6 month report

This report comes live from Serbia

Its been 6 months since the computer has been living under oil and it has lived up to all expectations. It has crossed the average life expectancy of a computer at home.

Present Rig
The present rig is slightly different from the ones on the pic... shall update the pics end of the month once i get back home. Ive thrown out all windows and switched to a stainless steel Tub. Does no justice to looks but then its practical... ive done away with the radiator and pump, installed a small fan 35 watt AC (used in deep freezers) outside the tub to provide some cooling. have attached some aluminum fins also. I was surprised the temperatures are just a degree above what i used to get with the radiators on.


Issues
No major issues... i had a problem with the SMPS , it turned out to be a leaking capasitor. Probably because of a manufacturing defect or power surge. Changed the cpasitor for Rs. 30 and its been up and running The parts look as if ive just got it from the store... no discoloration or signs of rust


Conclusion
the projects a success...i recommend it to people who have problems with high humidity. Cooling can be made much more efficient but then it was never my number 1 priority in the design requirement

Cheers

New Case Just In From The Fabricator




Just got a part metal part plexiglass case made. It should solve the heating problems even without the radiator. still plenty of work to be done

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
