Radiator Set-up Fan Analysis

Peeps,

Here I am again. As promised on the other thread that I'll share the results of the "Radiator Fan Analysis Comparison", now, here it is. From an Istoryan analysis...


Test Bed:

> Cpu: Intel SB i3-2120... OC'ed to 3.4+ MHz... no budget for the "K" cpu yet... hehehe...
> Closed LCS: Corsair H50... i'll call this as "The tank"... why? dako man kaayo'g cooling head (pump block)... bati kaayo'g nawong... joke3x...
> Additional case fans: 1 x 120 mm fan @ 1650 RPM (front intake) and 2 x 120 mm fans @ 1250 RPM (top exhaust)
> Used Fatal1ty F-Stream Tuning software to monitor the temperatures.
> Used Prime95 in load testing the CPU.


Set-up 1:
> Corsair H50 (original set-up)... 1650 RPM fan. Air flow was from "Out to inside"... Intake

Set-up 2:
> Corsair H50... 1650 RPM fan (push) and Cooler Master PMW 120 mm fan... 1650 RPM fan (pull). Air flow was from "Out to inside"... Intake

Set-up 3:
> Corsair SP120 Extreme Performance Edition... dual 120 mm... 2350 RPM... set-up for "push-pull". Air flow was from "Inside the case to outside"... Exhaust... mawala man gud ang view sa colored rings (in my case, red) if i-intake ang set-up sa fans. apil ra ba ni sa premium cost nya... tsk tsk tsk... hinoon, bugnaw ra man gihapon bisan nag exhaust direction sila. I haven't tested the dual SP120 EPE fan set-up on "Intake direction"...








Since it is winter here, in order to simulate the temp in Cebu, had run my room's heater for overnight @ 25 Deg C. Then started the testing. For the idle condition, its only windows desktop that's running (30 data points tested @ 10 mins interval... per set-up). During the load condition, per test, I run Prime95 for 1 hr then started to get the 30 data points (per set-up). Interval was 10 minutes per test. All cores were running including the Hyper-threads during stress testing.

Below are the results summary...







As shown on the graph, in the idle state, the temperature difference between the single rad fan (original set-up) vs the dual rad fans (Corsair's original fan and Cooler Master) is negligble. The difference was only 1 Deg C. While the difference when the dual Corsair's SP120 Extreme Performance Edition fans rotating @ 2350 RPM (max) was used, the difference was night and day. The temp difference between the H50's original set-up ang the dual SP120 EPE was about 9 Deg C @ max temp.

At load, the difference was around 3 Deg C at average between the stock fan and the dual Corsair SP120 EPE. This 3 Deg C delta from the base line (original set-up) is quite good already. If you love your CPU and would like to give some chill without the hassles and cost of an Open LCS, the addition of Corsair's dual SP120 Extreme Performance Edition fans is worth the money on your Closed LCS. It can give a new life to the single rad fan closed LCS. In this case, it gives a new life to the trusted work horse... Corsair's H50.

It would be better though if during the 1st purchase of the closed LCS, the dual rad fan model was chosen. It will save us, the buyers some cash... but this would greatly depend on the location...
