How loud is a 43dba fan for cpu?

I was about to purchase the Panaflo H-model to go with the xp-90 from jab-tech when i came across another link someone posted here and found an Ultra High version. Is this loud? 43dba? Would it require a fan controller even if its mounted on the heatsink and not on the case? If so,m which controller do you recommend?

Thanks.
 
The L1A will be plenty and quiet. 43 db is pretty loud. Its about as loud as someone operating a hairdyer outside of your 10 feet away from you behind a closed door.

30db is an acceptable amount of noise.

<24db is good for when you sleep in the same room as your computer.

This is of course only applying to fans of Panaflo, Yateloon, Nexus brands (and select others)
 
I wouldn?t consider 43 dBA to loud but you have to remember that the Panaflo is tested free air, once you mount it to a heat sink or case that 43 dBA is useless. Depending on the heatsink design you could be look at as much as 50+ dBA of noise, which I would consider loud.

I?d recommend a M Panaflo controlled by the CPU header on you motherboard, no fan controller.
 
well to me 43dba is nothing to my 4 tornados...

btw i just ordered that fan for my xp-90. will tell ya how loud and good it is when i get it
 
I've got dual Sunon 120's running @ 3100 rpm, 42db, 108cfm, and they are loud. I'm getting them replaced.

43dB is fairly loud. Be aware that many Panaflo fans sold here don't have the speed sensor circuit (but may still have a 3-wire pigtail). CPU fans must have a working speed sensor circuit. On Panasonics, it is usually the "BX" series that has the speed sensor (e.g. L1A=no sensor, L1BX=sensor)

.bh.
 
An ultra-high on a heatsink might defeat the purpose. Getting the cool to the HS, and the warm air out of the case is what we want.
The high speed might push the warm hot back into the case, instead of letting the case fan pull it outside.

I have an XP-90 mated with a Panaflo 92mm L1B (Low-flow). Panaflo's part number is FBA09A12L1BX. Rated CFM is 42.7 at 27 dBA. Very quiet yet good airflow. You can't hear the fan above the front-mounted 120mm Vantec Stealth in my LianLi V1000.

Anyway, this setup keeps my very slightly OC'ed FX-53 (206x12) between 39-41C in non-gaming apps. Runs between 50-60C while playing Halo online. The CPU works pretty hard feeding my X800 XT PE. This is with my case temperature at 25C. The Panaflo 92mm L1B fan also features Fan-Monitoring.

If you don't care about fan-speed monitoring but want added airflow without undue noise I would recommend the Panaflo M1 (rated 48CFM at 2450RPM @ 30.0 dBA). No speed-sensing rotor.

Please note that as Zepper said "many Panaflo fans sold here don't have the speed sensor circuit (but may still have a 3-wire pigtail). CPU fans must have a working speed sensor circuit. On Panasonics, it is usually the "BX" series that has the speed sensor (e.g. L1A=no sensor, L1BX=sensor)". So be sure you are buying a "BX" series fan if you want an RPM-Sensing model.

EDIT: I run the fan off the mobo's CPU Fan header so the fan speed is controlled by the mobo.
 
32 dBA was too loud.
24 dBA was too loud, but almost there.
14 dBA is just right for power supply.
Can't hear the HSF Zalman 7000, as it is barely moving.
This for a living room PC.

It helps when you run a XP-M that stays cool even when overclocked.

That depends on the mother board. Some need it, some don't care, but most will at least let you boot without it after enabling it in the BIOS.

I just replaced my single Sunon 120. How the Hell could you live with the sound from 2 of these? With 1, I thought my pc would get airborne.
 
Thermalright recommends the medium fan. High is a little extra breathing room (no pun intended), Ultra is unneccessarily loud. Even on a controller, high fans will always be louder than low fans.
 
i had it and powered it to see how looud nad it was more of a hum... it felt like it pushed as much air as a tornado. im a panaflo believer now =P. This was not putting it on any heatsink.. it would probably be quieter with it attached...and reviews has shown that a powerful fan makes it cooler.. a 92mm tornado on a xp-90 was as cool as a xp-120 with a low rpm 120mm
