koolance fan feedback/reliablility

Postby AgentX250 » Fri May 13, 2011 3:04 pm

Hi,

I am on the final leg of buying parts for a major overhaul of my current build (see sig), 99% of the hardware i.e. gfx cards, cpu, cables have been purchased with only the case, rads, and secondary psu remaining. I am, however, at a crossroads as it were. The fans I was planning on using were the xtreme turbines from aerocool (now EoL) with 89cfm and ~1.82mm static pressure. The rads that I will be using are the BI GTX360s and I am beginning to worry if these fans can supply enough pressure to be effective.

I began looking for good alternatives and started looking at koolance fans. The specs look great, especially for the price, but I would like to know how long they last. I figure the MTBF is probably 50k hours but would like people that own and use them to say how well/long they work.

I'm considering either using the 12025mbk or the hbk model, and will likely go with the latter since the price : performance difference is negligable. I would go with the 12038hbk but with an amp draw of .75 I would just barely be able to run 3 fans per channel on my controller I'll be using (which might prove problematic if I need to add more fans in the future).

so there it is, any hellp is much appriciated

The fans from my PC2-901 (80mm fans) are still running strong in another case. And the PC2 series is older than most. I have yet to have a Koolance fan fail, but I have had lots of other brands fail.

ya that's why I'm asking. I just lost a kaze 3000 that was only 2 years old (only had 1 1/2 years of use on it) and a 3 year old xtreme turbine. Both of which had a 50k hour MTBF.

Koolance fans aren't the quietest, nor the highest CFM, but they are reliable. I will give them that. I used to be a big fan of Silenx fans because of their high CFM to sound ratio, but only the 120mm fans seem to last longer than 6 months. I went through 5 of the Silenx fans for the CPU within one year. I gave up at that point and went with Noctua. They are ugly and expensive, but they last forever.
Koolance fans are for my non-noise-sensitive locations.

I'm not extremely concerned with the noise level so much as performance and lifespan as I will have at least one fan that is quite louder than the koolance ones I'm considering and I can always turn them down since they will be run off of a fan controller.

Thanks for the input, I wish more people would post though.

Then you should be quite happy with the Koolance fans. Yeah, the forums here have nearly died over the past few years.

I have a total of around 12 Koolance fans and some have been running for ~4 years. They are all 120mm in the two faster speeds.

I suppose I will buy them and see for myself then.

Koolance are on the noisey side but they get the job done. Noctua is where its at but they are expensive and ugly but you can always paint them black lol. I bought 5 koolance fans and having them full blast for the summer they are noisey but nothing like 5.1 surround sound will get rid of those pesky fans.

They don't appear to be much louder than my current fans, besides I'd rather have a slight increase in noise than a $400 fan bill (that's the bill for my fittings, or my rads, or the psu) it's easier for me to squeeze out an extra $100 than it is for me to find $400.
