Himo ko ani nga guide kai dili ko gusto nga ma experience ninyo ang akong bati nga kaagi. Nasayang akong GPU, nasunog ang mga ti-il sa mga ICs. Wala man unta ko nag duwa og bug-at nga games / apps nya wala pud nako gi overclock. Og ang hinungdan…
POOR VENTILATION!
So nagpatabang ko sa akong manghod nga M.E. gkan sa USJR – saludo ko ninyo mga taga USJR! Akong bro nag work karon sa usa ka company sa Korea nga mo design sa mga HVAC (Heating, Ventilation, and Air Conditioning) sa mga floating platforms, monster cargo ships, oil rigs, etc… cya ang in-charge sa Load Calculation. So enough MMK, nagpatabang ko…
Ingon cya “
ALWAYS TREAT YOUR CPU like a TOILET!” dapat e exhaust ang air, ipagawas ang kainit! lol
This guide helps you determine the RIGHT exhaust fan/s to remove the heat generated by your expensive toys inside your cpu case.
Step 1: Find out all the devices that generate heat like the psu, gpu, processor, hdd, etc. Find out the max TDP (thermal design power) of each device in Watts as the unit. Get the values at overclocked/load. Then sum them up and multiply it with 1.1 as the safety factor. The result will be your total heat dissipated, the symbol is Q = Watts.
Step 2: Make T1 as your Intake Temperature (varies depending on room condition), initially set it to 25. Then make T2 as your Discharge Temperature, initially set it to 35.
Here are constant values: Air Density kg/m3 as ρ = 1.2; Specific Heat of Air KJ/kg.K as Cp = 1;
Air Flow Rate ft3/min as φ = unknown
Step 3: The Formula:
φ = ((Q/1000) / ( ρ *Cp*(T2-T1)))*2117.25312
Example: (processor 100w + gpu 150w + hdd 15w ) x 1.1 = 291.5w is your Q
I did not include the psu. Since most psu have its own intake and exhaust fan.
φ = ((291.5/1000) / (1.2*1*(35-25)))*2117.25312
φ = 51 cfm
Step 4: Look for Fan/s with max air flow rate of 51 cfm. The higher the cfm the better. That would be your exhaust fan.
51 cfm is just an example. It varies depending on your current setup and calculation.
Position your intake fan directly to the device that generates heat so a positive/cool air can dissipate the heat generated by that device, and then place an exhaust fan to remove the negative/hot air outside the cpu case.
Do not allow a device absorb the hot air from other device, an example is hot air from gpu absorbed by the processor.
Arrange your cables so it would not disrupt the flow of air creating vortex.
Lastly, if your room temperature is hot like during noon, of course your cpu absorbs hot air. And if you feel that the exhausted air from your cpu is hotter than usual, then I would suggest to turn off the computer. Well, if you have aircon, then lasyhu! Pagbinun-tagay, hehehe
I know there are other ways; this guide may not be applicable to your rigs. Please feel free to post your suggestions and recommendations. And feel free to correct me.
