Corsair PSUs Fan RPM


svata

Recommended Posts

At the official website there are charts for the dba and watts. I attached charts for RPM of the fans and the watts.

 

I hope this information will be useful to someone who is looking for silent PSU, becаuse the whole thing with the "dba" is very relatively, but when you know the RPM the "picture" gets much more clearer.

 

The info is from : http://www.xbitlabs.com/articles/coolers/display/corsair-psu-roundup.html ; http://www.xbitlabs.com/articles/coolers/display/atx-psu5_15.html ; http://www.xbitlabs.com/articles/coolers/display/atx-psu9_4.html

This information is already on Corsair's website in the form of dbA vs Watts. Decibels are more important than RPM because you can have multiple fans running at the same RPM but at different dbAs. The reverse also applies, but either way it's down to the design. The dbA is what you're actually hearing, hence the "silent" part.

There are two reasons to write this thread:

1. Many manifacturers claim for false dba of their PSUs. For example Thermaltake claim that "Thermaltake Toughpower 600W (W0103)" produces only 16dba, but when I check the actual min RPM were 1000 rpm, and thats 140mm fan. For comparison Corsair TX-650 produces 21-22dba until 300W and its fan is 120mm and spins at 500rpm - you decide which of the two models is more silent. If I was searching for silent PSU, laying only on the information published on their websites - Thermaltake claims 16dba, Corsair claims 22 dba, I would preffer the Thermaltake because 16dba<22dba, but when I know the fan RPM it becomes obvious that 120mm fan 500rpm is much more silent than 140mm fan at 1000 rpm.

2. Some manifacturers publish information only for the noise levels of their PSUs and other publish information only about the RPM curves of their PSUs - in this situation it's difficult to compare the PSUs. For example Corsair gives you information only about the noise level - 22 dba until 300W for the TX-650, but Cooler Master gives you information only for the rpm of Silent Pro M600 - it spins at 700rpm (135mm fan) until 300W - so how to compare this PSUs if you can't see them in real world situation?

Now, when I know that the fan of Corsair TX-650 spins at 500rpm (120 mm) until 300W it's way much easier to compare them : Silent Pro M600-135mm at 700rpm vs. Corsair TX-650 - 120mm at 500rpm.

These are the reasons to publish this thread. I think it will be very useful to the people who are searching for silent PSU and came to this forum for more information.

You can have 2 fans at the same size and RPM and the dbA can still be different depending on the blade shape. Either way, if someone wants an unbiased report of a product they should go to a 3rd party, not to the manufacturer.

 

As per the rules the links to competitors' websites have been removed.

I apologize for the the links to competitors' websites. If the administrator thinks this thread is not useful I won't mind if it's deleted. I just wanted to save time to someone who's wondering what are the rpm of the PSUs.:):
