New HAF 922

post #1 of 9
Thread Starter 
I just unboxed my new HAF 922 and tested out the fans. I tried them plugged straight into the psu and into the mobo. I found that they were fairly low RPM and didn't seem to move that much air. They were pretty much silent, but they moved less air than my old v1 Antec 900. The 120mm fan on the back was moving significantly less air than the stock 900 fans that I have on a mixture of medium and high.

Is this normal? If so I'm not concerned, it seemed strange though.

200mm fans don't need to spin as fast to move the same amount of air as a 120mm fan. it just feels like less air because there is less being pushed out of one area.

they will probably increase on cpu loads and are very low when there is no load on the cpu aka not alot of hot air to kick out therefore it doesnt need to

try it with load

The 200mm fans are 700 RPM models, they won't move much air, but are darned silent. The 120mm as well, it's top speed is 1200 RPM.

If you plan to get better air flow, consider getting better fans, up to you to choose raw performance, silence, or a middle ground fan. Some good fans are Noctua's and Gentle Typhoons.

I was thinking more about the 120mm fan as it feels like it's hardly doing anything. Also I can barely feel the front 200mm fan through the cage.

It's not really a big deal because I can switch them with my 900 fans if it's a problem, noise doesn't really bother me. I was just curious.

And Biggie they're not PWM fans so the heat around them doesn't matter?

Yeah, i do advise you to change fans, unless you use a LOT of the silent ones, but they are better than no fans at all. And if they only have 3 pins, i doubt they are PWM or thermal controlled fans, but your mobo can be controlling them (most mid to high-end mobos can control fans even tho they are not PWM).

Just check the fan speeds with something like HWMonitor in both idle and load.

Well at the time I had them plugged straight into the PSU through the 4 prong molex. I just expected a little more airflow from a case called the high air flow. Either way, its a badass case and as far as usability goes it's way better than my 900.

Try to fill all of the ports with some 38mm Delta/San Ace fans, and you will really have a High Air Flow case .

All HAF cases have crappy fans from stock, but you'd be hard pressed to find a case with so many fan/rad mounts. Plus you're buying a case, not the fans.

Truche (True, Touche). I was going for a blue theme so I'll just replace the back 120mm with one of the Tri-Cools off my 900. I'll leave the top one alone. I'll probabaly throw one in the front too as that fan moves no air. Then I have a couple Slipstreams for the side and bottom. Like I said, I don't mind noise
