Looking for a really great fan to use on my 680i Northbridge which is now kitted out with a Thermalright HR-05 IFX. I'm going to take measurements later on but an 80mm fan with 25mm depth should be acceptable. Also it needs an open screw hole around the shroud so my fan clips can actually hold the fan in place! I was considering the Scythe Kama Flow2 80mm 2900 RPM fan but am open to alternatives. Besides the size of the fan it also has to be a 3-Pin powered variant so I can control it via BIOS.
these (http://www.scan.co.uk/products/80mm-silverstone-fm83-white-fan-quiet-1300-3600rpm) are mega. they mount in 80mm mountings but take up the space of a 92mm fan, so might not work for your application. They are absolutely great though.
Fractal fans have never really packed much of a punch in my experience. Nice fans but I'd like a little more performance for more money. Also you're right about Silverstone FM83, they just wouldn't mount properly to the Thermalright HR-05. Keep the suggestions rolling though!
If it's performance you want then you should consider getting an ex-server fan, like this Delta AFB0812SH for £9.99 with free postage. If you want to buy it new, it'll cost you £25. 80x80x25 4000rpm 46CFM 40dBA 510mA startup current 3-wire connector You simply won't get anywhere near the performance from the pansy "bling" fans in hardware shops.
Now we're talking! Get pretty decent nForce fan control via BIOS so it won't necessarily be at full whack all the time anyway. Gradually getting used to noise now as long as the performance is there. My E8500 is gobbling up the volts for decent MHz gains at the moment so I think a Northbridge fan would tip the balance even further onwards and upwards!
They are bling, and they can't push anywhere near 75CFM - not even half of that. Silverstone lie on their spec sheets, like most other manufacturers/vendors of bling fans. Delta don't pitch and sell their fans to the same market because they are purely quality and performance fans which are properly tested in a controlled environment - the performance doesn't need to be exaggerated for them to make sales, unlike Silverstone, Akasa, etc. This is what an 80CFM 80mm fan looks like - the Delta FFB0812EHE: it's 38mm deep, spins at 5700 RPM, and needs over 1 amp of current. Now that's a REAL no-******** fan.
Thats a man fan the sort you need a fan guard or you'll loose a fingertip in it How much heat do you need to shift though?
I used to have a 680i and it's a notoriously hot chipset, especially if you're overclocking. So the short answer is: probably quite a bit, hence the Thermalright heatsink on a frigging mobo chipset LOL.
Looks like I'm going to have to deploy cable ties ala LennyRhys! Too many capacitors in the way to install the fan retention clips so cable ties it is!
Cable ties are the way forward when the fans are powerful, seriously!! Incidentally the fan I have there on my CPU cooler is the big brother to the FFB0812EHE - the FFC1212DE. There is an "FFB" version but the "FFC" is four wires/PWM, so the perfect monster!!
I assume removing the sticker on the fan will reveal the inner workings on these Delta fans? I'll treat it to some fine machine oil if that's the case, using the old hairdryer trick to carefully displace the stick on the sticker temporarily.
Yeah you can take them apart like any other fan, but being high quality ball bearing fans you'd also have to take the bearings apart too if you want to re-lubricate them. Applying oil to the shaft won't make any difference really. Here are the two ball bearings from one of my Nidec fans, pretty much the standard as far as these server fans go - the collar inside the bearing rotates freely and very smoothly with next to no friction. If you think it is necessary and are very careful you can take the bearings apart, clean them with high purity alcohol and apply some new lubricant before closing them up again. Sometimes this works, but most often if a ball bearing is shot then it simply needs to be replaced rather than refurbished. I have several ball bearing server fans and have never lubricated any of them. The MTBF figure in hours equates to something ridiculous like 10-15 years of 24/7 use, lol.
Thanks for the advice. Also that Delta FFC1212DE fan, are you saying it's connected directly to the Motherboard CPU fan header? Peaked my interest in these server fans you git!
Heh I don't have any server fans connected to my mobo as they are far too greedy with amperage (eg the FFCs are 2.4 amps). I made a custom three-channel fan controller (a manual version of the 4-pin CPU fan header) and I use that to control my PWM server fans, although it will work with any 4-wire PWM fan. I currently have the controller connected to the PSU with a floppy power connector which limits power to about 4 amps which is distributed between the channels, but if I connected each channel to the PSU separately then there would be no power limit. This is why PWM fans are like Charlie Sheen: winning. More detail and discussion in my DIY fan controller thread! (Shameless plug)
Aren't those fans noisier than a space shuttle taking off? -_- Was looking at a nice Delta for a RAD, but found out they are EXTREMELY loud.
And if it's on a fan controller, it doesn't always have to be loud. My Delta FFC is at 800-1000rpm most of the time, at which speed it's quieter than a Gentle Typhoon but still provides adequate cooling. 4000rpm is there if I need it.
