Test Report: XSPC RX120

[AndreaBZ]

D12SL-12's (<600RPM-999RPM)
D12SH-12's (>1000RPM-1800RPM)
DFS123812H (>1800RPM-3000RPM)

Thats my thinking anway...good, bad, indifferent?

Martin has used
YATE LOON D12SM12-----------1000 - 1500 RPM
Scythe Ultra Kaze 3000------2000 - 3000 RPM

You in your test have used
Yate Loon D12SH12 and Scythe Ultra Kaze 3000

It seems that the Yates Loon D12SM12 behaves in different way by the
YATE LOON D12SH12

D12SH12... .2200 RPM 88 CFM 2200/88 = 0,0400

D12SM12... .1650 RPM 70,5 CFM 1650/70,5 = 0,0427

0,0427/0,0400 = 1,0682
1008 RPM of Yate Loon D12SH12 = 1077 RPM of Yate Loon D12SM12 (1008*1,0682)
I don't know if the calculation is correct.
It would be correct if the rpm were proportional to the cfm
Surely the two types of fans have a different behavior.
According to me the Yates Loon D12SH12 are fans diverse from the norm.....(Curved blade).

This makes difficult to compare the data of Martin (MLL) to those of Skinnee (SKL).


I have made this calculation done with the data of Martin and Skinnee..........
Published data:

Thermochill PA120.3 MLL.. RPM =1000 C°/W = 0,0307 (thermal resistance)
XSPC RSX 120 SKL......... RPM =1008 C°/W = 0,0663

Formula to calculate the thermal resistance of 2 XSPC in series:
C°/W two XSPC RX 120 in series = 1/((1/C°W rads A)+(1/C°/W rad B)) = 0,0663 / 2 = 0,03315

Difference C°/W Thermochill PA120.3 - C°/W two XSPC RX 120 in series = 0,0307 - 0,03315 = -0,00245

what multiplied for 200 watts it becomes 0,49 degrees.

Difficulty to believe that to 1000 RPM and 200 watts,
Between a thermochill PA 120.3 and two XSPC in series there is only half degree of difference.

According to me to use more than two types of fans makes the most difficult the test.

Besides the Yate Loon D12SM12 of Martin (min 800 RPM)
a good fan is
Fast Version: Scythe S-FLEX SFF21F (1,600 RPM)
550 RPM > 1590 RPM
