I'm looking for three 90 mm fans to replace the loud stock fans on these Supermicro 5-in-3 units.

 

The goal here is to be as quiet as possible while still providing enough airflow to keep 5 green drives adequately cool (below 40C).

 

Extra bonus points if the fan has a 3 pin connector that can plug directly into the back of the Supermicro unit.  However, no big deal if they use the standard 4 pin connectors and have to be powered directly by the PSU instead.

Check out the Silent PC Review site.  They have a recommended list for fan from 80mm to 120mm.  Do some checking of the CFM for the stock fans and then compare that to the list on SPCR.

The recommended fans list on silent pc review seems to have been last updated in 2007....  or did i miss something?

I changed mine to the Geild Solutions 92MM fans.(I cannot remember the model number).

 

They are quiet and have passed the 1 year (4 season) temperature and sonic tests.

 

I know another member here used them after my mention.

I learned about them from the Supermicro Review on Newegg.

I would buy them again if I had to.

Thanks Weebo.  Was it one of these?

 

GELID Solutions FN-FW09-20-B 92mm Gamer Fan WING 9 Blue - $20.99

 

GELID Solutions FN-TX09-20 92mm Case Fan - $12.99

 

GELID Solutions FN-SX09-15 92mm Case Fan - $10.99

 

I'm leaning towards the $12.99 one as it offers variable speed (and the lowest dBA rating).  However, would the Supermicro cage be able to vary the fan speed, or would it run it at full speed all the time?

Variable speed fans will need to be connected to the motherboard or a fan controller afaik.  There is a thread about getting fan speed control through unRaid somewhere.

 

be aware that usually low noise = low speed = low cfm = not much cooling.   if you want quiet, efficient cooling you need 120mm fans.

Understood, thanks.  Unfortunately 120 mm fans aren't an option with this build.

Mine is a 2000 RPM 4 PIN unit.  I don't think I spent more then $13.00 each.

 

I just checked my old invoices, I bought them in March of 2010.

I thought I was going to plug them into the motherboard for monitoring, but I plugged them right into the supermicro unit instead.

They are quiet and have cooled adequately throughout the summer. (even without air conditioning in my home).

Thanks again.  I'll probably end up going for those.  I didn't think the Supermicro unit could take a 4 pin plug.  Do you just leave one end of it hanging off the end of the connector?

Yes works equally well. I think it runs at full speed.

I bought these knowing my motherboard had the 4 pin pwm capability. The motherboard manual states to use all 3 pin or all 4 pin fans.

In any case I popped the 4 pin onto the 3 pins directly on the cage and it works well.

noctua nf-b9 (http://www.newegg.ca/Product/Product.aspx?Item=N82E16835608005)

this is what i use and, imnsho, totally worth it.

btw, i got them from ncix, cheaper than newegg.

cheers.

 

 

Might want to buy from here. http://www.jab-tech.com/Noctua-NF-B9-92mm-1600rpm-Fan-pr-4438.html

 

JAB-Tech is a great place for fans.  Price about same as NCIX, but shipping a lot less.  Likely faster too to US addresses.

Interesting.  What are the low noise adapters and ultra low noise adapters?  Will they still be compatible with the Supermicro cages with those adapters installed?  They are certainly more expensive, but quieter too, and the airflow is impressive.

I believe the low noise adapters are adapters that converts the 12V to 7V or 5V (for ultra low noise).

 

And one should check amazon.com for the Noctua stuff (free shipping...)

They also have the rubber mounts. I'm not sure how effective they are.

I'm pretty happy with my $8.95 fans I'm not sure the extra $10 is worth it for those fans.

 

 

I think you are right, Weebo.  I'll go for the Geild fans and save my client some money.
