If the fan header is not providing enough power it might be worth looking at drawing some from another source either the 12V plug directly in the back - or maybe running the fans off a USB port?

Some good news. I removed one fan and then turn the other fan around to blow cool air into the case instead of drawing hot air out. Now, my idle HDD temperature has falled from high of 47-58 degrees C to 41 degrees C. Also under load, it has been able to maintain the case temperature at 44 degrees C. ktula.com/2006/09/18/its-getting-hot-in-there/ |

I also unplugged one of my fans and the 2 existing ones run faster as well. I have added a warning to the first post as overdrawing the power from the mobo header might cause problems.
Can someone with an actual knowledge of electronics suggest what is most important in looking for replacement fans to run off the motherboard header? Amps, volts, watts? Any ideas what the max output of the header would be?
eg 2 x 40x40x10mm fans will produce 0.14Amps which is the same as a 20mm fan - not sure if this is better or worse?

Leyton,
Have you tried flipping the fan you installed on the side of the case to have it blow air into the case, instead of drawing air out? I find that if i set the fan to blow air into the case, i can get the idle HDD temperature to go down to about 40 degrees C (room temperature of 75 degrees F). However, if i flip the fan and have it draw air out of the case, the idle HDD temperature temperature would rise to about 46 degrees C.

What is the difference between ball bearing and hypro fans?  |

Here's the ADDA description for HYPRO fans: www.adda.com.tw/engineering/info5-1-1-s.htmHY-"Hydro-dynamic wave" PRO-"Oil protection system" 1)By means of reducing the surface friction area between the shaft and the bearing, the bearing temperature will be reduced naturally when HYPRO fan operates. 2)The unique bearing construction can store and maintain more oil volume with a oil-cycling protection. 3)The bearing is made of a new alloy material harder than bronze. These are the reasons why HYPRO fans can perform longer life expectancy, lower noise, and most of all, steadier at high temperature than sleeve, ball bearing fans. |

... so why does mine sound like it's grinding coffee then  even though it is only a few months old I'm not quite ready to cut up my case (and anyway winter's coming and the drives finally sleep with the new firmware so it is a whole lot cooler that it was in our blistering July) but I am looking at the "external larger fan with fan adapter" route |

Have mounted a 120mm fan on top of my Thecus N2050 and will see how that goes before considering fitting 40mm internal fans to the sides. ;D
Had to buy a circle hole cutter to cut such a large hole. Seeing as you guys suggest blowing the air in rather than out, I might reverse my fan.
It's a S-Flex model SFF21E which is supposedly reasonably quiet. Running it via an old mobile phone charger powerpack I had sitting around.
The fan is now being returned for warranty. Lucky I had a spare of another brand.

caleula,
where did you get the circle hole cutter ?

Well, cut a 40mm fan hole on one side of the case and didn't allow for the top cover middle slide lock, so the hole is in the wrong position. Suggest nobody cut holes for side fans. They don't appear to be necessary, just the existing exhaust fan and a top-mounted 120mm fan.
For the moment I have taped over the hole, but with a Coolink SWiF 120mm fan on top blowing downwards, the Thecus N2050 is as cool as a cucumber running two Seagate 320GB SATA II drives. This fan matches the enclosure (a blue one) quite nicely.
Also noticed that one of the internal circuit boards is from the N2100. Have also improved the LED front-panel lighting by placing black plastic LED mounts over them. This has concentrated the light forward and eliminated the sideways glare.
Well, the Thecus N2050 is still running cool after about six hours, but the computer didn't show the Raid Array when I came back to it after dinner. I switched it off and back on again and all was okay. A glitch in the system?

I'm sure you do, but I haven't a decent digital camera/phone. For the present setup, picture a translucent plastic fan with blue blades. |

caleula, where did you get the circle hole cutter ? Off eBay, but it's now up for sale at half-price. Has only been used once and did its job. |
