Re: I've decided....
 

I've got the computer in my car and im going to build it and heres the deal
I got a Core i52500k, 8 gigs of corsair dominator GT, a gigabyte P467 chipset and now im going to put it together so cheers... and thanks everyone for suggesting me to get a i5.

Should be fun.

On that subject, I tried hooking up the two H70 fans Corsair sent to my H50, which are 200-300 RPM faster and around 2CFM higher airflow each than the stock H50 fans. All it did was make more noise and although it dropped idle temp 1c, it actually raised load temp 1c, and this was after thoroughly cleaning any dust off before attaching the H70 fans.

Out of curiosity and a desire to run matched fans, I put my two rear case fans on the H50, which are 200RPM slower and around 8 CFM less airflow than the stock H50 fans. Wouldn't you know it I get roughly the same results as the stock fans.

That tells me there is far more at play than mere RPM and CFM when it comes to rad fans. You have to factor in static pressure and concentration of airflow, not just volume of airlfow.

If I ever see them at a killer price, I may eventually try a couple of Silverstone's air channeling fans. Supposedly they really do direct the airflow more efficiently, and they're pretty low noise too.

That being said, I think what is more likely going on here is the fact that a small sealed WC unit like this can only perform so well regardless of fans used and reaches a saturation point at a certain temp.

After seeing the minimal temp differences on benches of the H70, I'm also doubting it's smaller pump/WC block assembly is any more capable than the H50's. It's likely just more efficient for it's size producing the same pressure/cooling in a smaller package. I'm sure the real reason the H70 is slightly better at cooling overall is due merely to the thicker rad, which is no doubt why they had to make the pump/block unit smaller, to have room to install the inner fan.

Get a couple of 38mm fans and you'll be set. Panaflo's are $4.25 at crazypc atm. Might want to pick up a couple of them

Re: I've decided....
 

Even if they are somehow more efficient at perhaps channeling the airflow, I really wouldn't want something THAT space consuming. Besides, I checked and they only show 2 DC 120x38 Panaflos at $8.50 and $13 and they have a pretty loud db rating.

Re: I've decided....
 

Everything is 50% off at checkout.

Even a single panaflo would beat out two 25mm fans. Its all about static pressure, and those rads need high static pressure fans. As far as being loud, the medium speed one isn't loud at all. I've got one and I was kind of disapointed since I thought it would be louder going full blast.

Re: I've decided....
 

CFM means pretty much nothing when you're talking about rad fans. It's all about static pressure.

I was using NF-P12s, which have, I think, 1.31mm static pressure. I then switched to Akasa Apaches, which have basically the same specs, except 2.64mm static pressure. Saw a 3* idle drop, and 8* load.

Re: I've decided....
 

Funny that the stock H50/70 fans are actually MADE by Akaska. Is there ANY site that sells fans where they list static pressure specs?

Re: I've decided....
 

doubt it. only delta and a couple other server-level companies even test for it

Re: I've decided....
 

Well I refuse to go high static if it means high noise (even over 30db), and high efficiency like the NF-P12s means high price (not to mention FUGLY!). Guess I'll wait until I get a GPU that warrants a higher OC on the CPU. Until then I'm good with it the way it is.

Truth is I'm starting to recall how much I hate radiators after seeing some minor fin dings after taking this stuff apart a couple times. Something tells me I'm eventually going to chuck this thing and just get a decent affordable air unit.
