SP120 High Performance low RPM problem

Hi,

 

I got two SP120 High Performance fans that I use for my H100i.

The problem is that, one of them is running slower than the other.

I manually maxed out the speeds in bios settings.

Its like around 600 RPM slower than the other.

I tried connecting it to different fan headers in the motherboard.

But the one is always slower than the other.

Do I need to get it replaced?

 

Please let me know.

Thanks.

What are the fan specifications for each of the fans?

Are you using the included voltage step-down adapter?

 

SP120 HP (2350RPM)

Operating Voltage 7V - 12V

Power Draw 0.18 A

 

SP120 QE (1450RPM)

Operating Voltage 7V - 12V

Power Draw 0.08 A

The box says 2350RPM.

And I'm not using any voltage step down adapter.

Anyway...

Lets say I connect the fan in the mobo fan header and check the RPM in bios.. it says around 1300... But when I connect the other fan to the same header and check, it says around 2000.

So does that mean, its defective and I need to get it replaced?

Both the fans are HP edition.

I tried connecting the included SP120 from the H100i. They are insanely fast btw. The only reason I bought the new fans was cos of the red rings :)

It's most likely faulty. Request an RMA to replace the fan and make sure you upload a picture of the invoice as proof of purchase.

Hi there,

It probably is faulty.

I took it out and now using it as bottom intake...

And I replaced the radiator fans with the stock ones... SP120L that came with the box.

They are now much better.. Temps are cooler... CPU @ 22C

I'm not gonna RMA the fan.. The process is a nightmare.

 

Thanks for your help (:

If you do not want to RMA the fans and you are still under 30 days, contact your seller and replace it through them. It's better to have a fan that is suppose to perform at its rated specifications.
