Saw your Lian Li mod bro, sweet stuff!!

if it's exhaust fans, look for one that has the highest CFM will do, can give the CM jetFlo a try or if you want a quieter option maybe a BitFenix Spectre or Corsair AF140... all have LEDs

180mm fans are hard to find.. let alone PWM... most big fans in the market are 200mm and above.. why would you wanna replace the Air penetrators??

yeah this is one alternative... available locally?? I said hard to find, but I meant locally, if yo can get a forwarding company, you can get them from overseas I suppose

That is hard to pinpoint, fans in general are priced almost the same across most shops

Well AC 8cm was in the market a while back but it has been missing for a long time... no idea where u can get a new one.. but there are generic 8cm fans around LYP that's easy to find... as for dust filters, try looking in the garrage sale section

Artic F12 are rare because everyone is buying them, they sold out once they hit the shelves a few months back but now I totally don't hear ppl talking about them anymore

it should be two different editions as each only has either red or orange LEDs... not too sure what is standard to you but red is red to me lolz

are you looking to mount on a CPU cooler / RAD or chassis intake / exhaust?

I'd recommend you getting 120mm fans from BitFenix or NZXT for chassis fans since they have the white/black design to them as chassis fans

for CPU cooler or RADs I'd recommend something like the Noctua NF-F12 PWM which are pretty sweet for the performance despite the hefty pricetag.. and if you don't like the colour, you can opt for the Redux line (which cost less) or the IndustrialPPC models (Warning: premium product) as well

I would use it an an intake so that dust will only accumulate near the intake as opposed to the shole chassis becoming a vacuum cleaner

erm.. assuming that the fans are all the same type inside your chassis, it's a positive flow... instead of buying fans, I suggest removing the bottom intake and see if that's any better....

Jetflo fans are not quiet..... go for something like the Noctua or Noiseblockers especially for the CPU coolers

230mm BitFenix has them..

not too sure of NZXT and CM storm...200mm for sure but 230mm have to ask

woo... this one is slim type?? won't it be loud?? even the Noctua Industrial PPC 120mm at 3000RPM already too loud for me

IINM Corsair's AF series has non-LED versions

normal fans should suffice, the idea is to draw more air in instead of forcing air through tight gaps.. but if you can get good SP and Air flow why not?

Actually you have to check.. some 140mm do have high static pressure rating like the TY141 from Thermalright or SP140 from Corsair, what is your intended application for these fans?? rads?

BitFenix Spectre Pro LED 120mm

owh! those are great as well, directional airflow does wonders as seen in my team's review of the RV04, FT04 and RV05

well actually fans are at that price for a long time, it all depends on what you're looking for, there are still RM10 fans around but for most of us here in this thread, we're likely to be looking at better fans to suit different needs

inexpensive.... very rare have 15mm fans.. I only know Idealtech carry prolimatech ones that are 15mm but not too sure if you would call them inexpensive

Just pick a normal transparent blue LED fan will do, these are normally quiet because they don't push a lot of air... normally for decorative purposes

If you want a good one, I recommend the Spectre Pro from BitFenix, loks great, silent but... it's RM59 for a 120mm haha

so far I only say Noctuas with the PWM option on the 92mm range

I have to agree with Stuart on the CM fans on this one

erm.. you will get a molex to 3-pin adaptor when you buy the fan, it's included inside the package the last time I bought mine.. else, you could just buy them separately, it's quite cheap, or you could ask if anyone had any spares

Both fans CM and Aerocool are okay in my books, just see which one you rather have, CFM and Air pressure rating may be inaccurate at times

So you're saying that your system during gaming is at 65c? thats a great temperature actually, considering that you're running on Sli config adding extra fans might lower down it further but not much.

There are other things to consider as well such as your room temperature, I mean think abt it, if your room is hot, then you're drawing in hot air as well so placing your PC in a good and airy spot will definitely help with your temps aside from adding fans..

Having said that though, it is better to invest in a good quality fan, ones that don't fail you every few months
here are some that are trustworthy in my books
BitFenix Spectre Pros - solid and good looking, performance is not bad
Cooler Master jetflo - may be slightly loud but good airflow
Cooler Master silencio - only available with their AIO unfortunately
Artic F12 - very rare nowadays
Noctua - all grades, all varieties except LED but 6 years warranty and damn good fans

Nice info!! thanks!

since they're the same fans, I'd take the 140mm any day if I have choice like you, basically they tend to be quieter while pushing at least the same amount of air

Enermax fans are okay, do go for the 140mm, really recommend because of the quieter operation
