Future Proof(ish) Fan Purchasing.

post #1 of 10
Thread Starter 
I am interested in getting a couple new fans for my 280mm AIO radiator but I want to do some future proofing in my fan purchase. I am planning on going full watercooling in a year or so (currently saving up), so I want the fans I purchase now to be compatible with my future radiator. I am thinking about getting four 120mm radiators and four 120mm to 140mm fan adapters because it looks like most radiators use 120mm fans over 140mm radiators. Do you think this is wise or should I just go with the 140mm fans?

That's kind of like saying you're going to be buying a new car in a year, and what tires should I buy now that will work on my new car ...without knowing what new car you're going to get. Kind of a recipe for disaster.

The fans you will use will depend on the rad you buy, and the rad you buy will depend on how much heat you have to remove and what water flow you will have.

Come on Bill. While I can see some truth in your analogy, it has many flaws.

While radiator size / area in a loop is determined by many variables, the most critical factor to consider at this time is only what size fans these future radiators will use; 120mm, 140mm or 180/200mm.
With quality radiators they will work well with a large number of different hi-pressure fans .. any one of which HellBOmb can buy now and move to radiators if and when he goes H2O.

But we do need to know what fan size the radiators HellBOmb plans to get will use. thumb.gif

Hmmmm

Then which of there 5000+ fans?

Seriously, besides the points noted above:
Fin spacing of the rad?
Fan Thickness, 10mm - 38mm
Push, Pull, Both?
2, 3, or 4 pin?
Color?
LEDs?
There's probably more, like does HellBOmb want to watercool just for looks or will this be an all out performance setup?

Didn't mean to get too into depth here, just curious about what size fans other people think I should get for the best possibility of them when I switch to water cooling in the future because from what I can tell 3x120mm fans are the most popular for water cooling radiators. (I do plan to go for performance over looks). I didn't want to get into specific fans because I didn't wanna be one of those people who can't google stuff for themselves but since you asked I was thinking about getting the EK-FURIOUS Vardar FF5-120 (120mm) fans. I have been scowering the forums for the last few days and it seems like they are Vardar fans are some of the best for radiators and the FF5-120s have the ability to achieve higher RPMs if needed than the similar fans of the series. Plus I really like what I have heard about their customer service.

If you're getting vardars get the 120mm F4ER they have the low range of F2s and the high of F4s, I would avoid the FF5s as they are loud at the higher end.

What KaffieneKing said. If you get Vardar get the ER version. Otherwise they will not idle down. There are a lot of complaints about the coil whine from the Vardar motors. Just something to consider if you don't want to hear that kind of thing.

What Bill is saying is true, but much of it is not as critical as he is making it sound. Take a chill pill Bill. biggrin.gif
There are many fans that are just plain good fans to use for almost any application. Fans like 1850rpm or 2150rpm PWM Gentle Typhoon for example. They idle down to low speeds, are quiet, have good P-Q curve and static pressure so move a good amount of air even with high FPI radiators or high restriction filters and grills.

To me, future proofing sounds like buying a fan with a long life span.

For that reason, like others here have suggested, I recommend that you buy Gentle Typhoons for "future proofing".

I suspect that the Vardar fans will not last as long as the Gentle Typhoons. There may be QC issues too.

Official stats as per EK:
https://www.ekwb.com/shop/ek-vardar-f4-120er-2200rpm
- Bearing durability: 50.000 hrs @ 40°C (MTBF)

By contrast, the Nidec Gentle Typhoon lasts as long as 100,000 hours at 35C, L10. Note that L10 is far more stringent than MBTF. Actually, the L10 of the Gentle Typhoon is 60,000 hours at 60C.

The closest equal to the 2200 rpm ER Vardar would be the 2150 rpm Gentle Typhoon PWM version.

2-3 companies make almost all the fan ball bearings in the world, so you can have as many specs listed as you want but it will be mostly due to just different testing methodologies. As far as going between 20k vs 40k vs 50k vs 100k MTBF, other issues are more likely to pop up before you ever hit that many hours of operation anyway.

Indeed. thumb.gif
40,000 hours is more than 4.56 years of constant use.
50,000 hours is more than 5.7 years of constant use.

Most of us will likely be using different fans by than.
