this one is pwm four pin that is a must
Current: 3A
Power: 36W
Line 4 pwm Intelligent Speed --------- good
Speed:4000 ± 10% RPM -------------- too slow
Wind: 190.30CFM --------------------- should be over 200 not under.
Noise: 59 d-BA
Working life: 80,000 hours
but it is 4000 rpm which will very likely be too slow
the other one you picked seems to be 3 pin
this one is more likely to be what you need
MODEL:PFC1212DE
Refurbished--But the performance is high quality
Best Fan for GPU miner
Brand:for delta
Size: 120x120x38MM
Voltage: DC12V
Current: nominal 4.8A (12V current rating 2.98A, for delta fan deficiency is serious, understand stock friends all know, 12038 fan could reach such a high current is this, there is no other comparable to that of his. )
Air volume: 252.85CFM (7.16m3/min)
Air pressure: 1.412 in H2O (351.7 Pa)
Weight: 0.351kg
Noise: 66.5 dB (a)
Power: 57.6W
Speed control: support motherboard PWM speed control
Rpm: 12V under 6500 RPM
Fan frame: injection molding, glass fiber +VO PBT+30% grade flame retardant;
Blades: injection molding, glass fiber +VO PBT+30% grade flame retardant;
Fan rotation direction: from the fan blade direction to counterclockwise;
Operating temperature:-10 c to + 70 degrees Celsius;
Storage temperature:-40 degrees c to + 70 degrees Celsius;
Bearings: high-precision ball bearings;
Power range: rated power supply plus or minus 15%;
Insulation resistance: more than 500 mohm;
Withstanding voltage: foreign exchange leakage current 0.5mA 500V/1 minutes;
Operating life time: when the ambient temperature is 25 degree 80,000 hours.
Motherboard PWM speed control cases, adjustment to the 10% following the speed of 1050 rpm, 10%~100% adjust the fan on a level increase of 405 per turn, due to the boards current limiting, so not up to 5500 RPM.
this one is pwm ------ check
this moves 252 cfm ---- check
this one goes to about 5500 rpm --- check
these are 4 pin --- check
order 2 not one extra is better if you have a few of the miners.
keep the old fan as you may need to move wire order. when you get the new fans. post a photo of the four pin plug on the old fan and the new fan.
red black blue yellow wires need to match the same order on both fans.
if they do not I will teach you how to switch the wires without cutting them.
