Naturally Aspired PC WaterCooling Club

As a rule, 38mm fans have much more static pressure than 25mm fans. Panflo and San Ace are both industry standards.

True!
and Panaflo, Delta, EBM-Papst and San Ace are all industry standard:)
 
No, Push/Pull is definetly the preferred option, but not certainly necessary, if your push fans are very strong...would be for price efficieny, not for maximum performance in that case ;)

I wouldnt trust the most ratings for static pressure on fans, often they are way off, very overestimated. I have a good bunch of Fans here, and those that have high pressure at low RPM nearly always have exotic, often upwards tilted blade designs.
Enermax Magma,white Silverstone 1202, EBM Papst... probably also Noctua, San Ace, Delta and the like, even tho i didnt owned one of them till now (Designs are often similar, so is the Performance)
Generally you could say, the fewer the blades,the more RPM and the more agressive the upwards angle of them, the higher the pressure the Fan should produce ;)

In my opinion, good push fans are the Enermax Magmas for sub-2000 RPM, any 2000 RPM+ fan that fits your purse, and if you want to invest in something durable and variable, a few Delta-like fans, preferably under 4000 RPM, 3500 would be fine in my opinion.

I guess you could turn the Fans around to pull air from the direction of the case, if you would install a small selfmade duct, that would ensure, that all the hot air from the VGAs gets directed to the ground, and not upwards :)

Thanks for your responses guys. I appreciate all of your answers and I believe everything you gave me will assist in my next expensive and inexpensive upgrades to my Loop... and soon in the future loops.

My Next short term upgrade will be a better block and low Noise but high pressure fan. My longer term upgrade will be another loop to cool my cards for all around better temps in my case and just in general. As far as long term upgrade to my Current CPU loop.... I will upgrade the Pump and Rad but since what I have right now is not bad that will be my longer term goal with my current loop.

So with that said.... if it were you guys right now who had to buy some decent fans. And you were looking for quiet fans that have decent static pressure what would you get? I have some Delta fans already but the noise from those bad boys are horrible. One of the reasons I went to water cooling was besides better performance.... less noise. When your equipment is starting to creat so much heat and the only way to control it is to have fans that are as loud as a jet that is a problem. So any suggestions on what you would buy if you had to buy a fan with these qualifications today???

Thanks again! :toast:

Cough nidec cough

You both are right. Those are also some damn nice fans. I left out Delta and Nidec because they sound like vacuum cleaners:laugh:

Well, I have bought 7 Gentle Typhoons this month:D The 1450rpms are almost totally silent, and the 1850s are pretty damn quiet as well. The GT 1450s are in push/pull, I don't think they would do as well with just two.


That being said, I still love the Panflo L1s I just swapped out with the GTs. They actually performed the same at about 12-1300rpms and were about the same noise level. Nice thing about those was that if something got hot, I could crank them to 1700rpm and things would cool off quickly.

If I were buying just two fans, to work in all situations, I think I'd go with the Panflo L1s. If I were buying 4 for push/pull, I'd go with the GT 1850s and a fan controller. I do anything I can to avoid noise.

EDIT: Hell, I forgot I have a Youtube vid of the noise from the Panflos. I took it for ERazer who, incidentally, uses GTs.

Hey thanks man nice and informative!!! I will definitely look those up when I get a chance tomorrow! Nice video too!

Thos fans weren't bad at all even at top speed! Mega thanx again!! :toast:

After thought.....

I was looking through my spare fans and I came across these. They were given to me for free and I know nothing about them. The brand name is.... Sunon. According to on store online they run @ 3100RPM but only have a Noise level of 41DBA would you believe it??? Here they are...

http://www.aerocooler.com/shop.cart?action=ITEM&prod_id=FANSU1238

That seems too quiet for that speed. Or is it because they are 120mm x 38mm would that have a effect on their sound??? I can hook them and find out myself but i just thought yo might know off the top of your head.

They are performant, but sadly i dont like the looks of them. could be a cheap alternative for noise resistant Enthusiasts tho ;)

I would never buy me anything High Performant again, except EBM-Papst fans.
They simply impressed me with their power and quality, even tho, that quality has a price. compared to them, even a delta is cheap.
There are a lot of similar performing fans, but most of them click at low RPM. These wont. ;)
Also, the Blade Design is FAR more superior than any kind of blade design i have seen on 38mm fans before. The Blade has up and downwards protruding Winglets, and between the blade and the fan casing, there are probably less than 2mm space, the fan is VERY tightx

Sounds like you found a good Rad fan, they should be a bit noisy tho, from my knowledge.
Try them at 5, 7 and 12v, and find the speed/noise level you like... if they dont annoy you, they should be fine, and that would save you money :)

does anyone have a recommendation on a few(3) 80mm fans for a koolance PC2 radiator? the ones I have now are old, loud, and move _____ for air....
 
A pleasant surprise, my new rad showed up today. Gary at Sidewinder got it off early on Thursday, so I am really happy I decided to order from him. Good shopkeeper. Anyhow, had to come up with some mounting ideas, since it is so much thicker than the old one. Turned out pretty good, although I'm going to have to mod the top. Maybe. XSPC markets the RX as a two fan rad, and I guess they are right. Makes a funny windtunnel noise in push/pull. Still a lot of air in the loop, but surprisingly, as well as disappointedly, temps are damn near exactly what they were with just the tripple!?! I'm hopefull that when it's all bled I will see some gains.

Here are some old pics of my humble rig, hopefully you won't get angry if you find it ugly :)

I'm actually waiting for my new casing (lian-li pc-a04) and I'll be modding that one to fit a 2x120mm and 1x120mm rad, and I'll also change to white xspc 3/8id 5/8od tubings since I find the 7/16 to large for that matx case :)

MT Alex, yeah, he's a great guy.

Nice case Zhadlp

Nice case.... I just went Lian li myself although I went with PC-V1020
 
There's only 1 local supplier in the country though, and stocks won't arrive until feb 25, so it's gonna take a while before I get what I paid for :(...

I just received the bezel, replacement case feets, and some powdercoated mesh the other day for the mods I have in mind though, so I can't wait to get my hands on the case itself, hehehe :D
 
@MT with my top mounted rads i had to flip the case on its back and top to fill it
 
Alright, my gpu idles right at ambient room temperature, and peaks about 13-15 above ambient. Meanwhile, my cpu usually idles around 13-15 degrees above, and peaks somewhere around 34 degrees above. Does this suggest that I need a better block? Currently have a Phenom II 940 at stock volts, and a Danger Den MC-TDX. Doesn't seem like a bad block, heavy copper.

Also, my idle temps are worse with the new XSPC, could this be reflecting more restriction in the loop? I hope not, I'm pretty fond of this quiet pump. I ditched my 655 vario for it.

the tdx is a nice block... but it was originally designed in socket 939 days (i also have one which cools my delidded 3800+ 939 fairly good)
i guess you need a high performance block, with modern jet impingement design, like a Heatkiller 3.0, and EK Supreme, Koolance 360 or so, and it also can be that your pump limits you... i can tell from experience ordinary laings are a good choice, as you can mod each standard laing with blue impeller, to a laing ultra, which is fairly quiet also, but packs more punch than your pump i think:)

Mod the Laing D5?

it is more than likely the waterblock i ran an old maze 4 for a while and the dtek fuzion v1 i have is a good upgrade with a jet in it it gets better temps too.
 
Heck, I have an old v1, with all of the nozzles. I upgraged, or so I thought, to the DD. To be clear, it is the newer MC (mulit-core) TDX with all the pins, not the old standard TDX. Gee whiz. It's always something. I thought I was finally going to have my loop just the way I wanted:ohwell:

mc-tdx-AM2-top-600w.jpg
 
The fuzion lookls like its got a bigged chamber in itt...
 
Which nozzle is best in the v1, the one with the single stripe in the middle? I might dig mine out.
 
Nope that's the quad core insert the 2nd smallest insert is what was recommended to me
