So you make a claim that a certain type of fan is better even when being used as a case fan (not the intended application). I ask you for the data to back up that claim. Of course tou don't have any. But say instead I have to come up with data to prove you wrong? I don't think so. That's...
I don't really see how this is so much Apple's fault. Pegatron offered them lower prices than Foxconn. Apple went with the lowest cost supplier they felt was competent. Turns out Pegatron is working their employees to the bone.
And you have data to back that up? None of the cases I've bought in the last 5 years have restrictive grills. Exhaust fans don't even have filters. A fan that works well on a radiator or heatsink generally have higher static pressure. I haven't seen a single shred of data that higher static...
Split some of the outputs. However, even with the same voltage or PWM signal, the fans aren't all going to run at the same speed. There is some unit to unit variation.
If you want a case fan, the through the rad data doesn't seem like it's the best data set to be examining. I'd rather see the same sort of data running free air, or through a much less restrictive obstacle.
Isn't that what PWM controlled fans are for? The fans are controlled by the motherboard based on temps.
FWIW, good fans are a niche product and are priced accordingly. It seems like we're not using the same definition of good though. You seem to be after high CFM. Most people these days are...
The die hard quiet cooling crowd think the Redux 140mm version is better than the newer A model.
I found a Prolimatech Blue Vortex 140mm to be the best case fan for one of the spots in my HTPC blowing across the GPU. After adjusting each fan's RPM to the threshold of audibility it outperformed...
Depending on the case 140mm fans with 120mm fan holes don't mount nicely. My Corsair 600Q is like this.
Well, what are you expecting and what are you getting?
Well, you don't have to put a fan in every spot. You can leave some of them open. Are you having problems with the thermals of components in the case? I'd be tempted to put the 1 or 2 in the front, one in the top blowing out and leaving the rest open.
Don't fight physics. Heat rises. Don't try to blow cold air down. I have an inverted ATX case (Corsair 600Q) so the graphics card doesn't heat the CPU. A front 140mm fan blows right across the graphics card pushing the heat out the back of the case.
Best at what? Are you pulling air through a filter or some other sort of restriction? Do you need PWM control?
I've been trying to find high airflow and quiet 140mm case fans myself for my HTPC in a Corsair 600Q. I'm planning to test and compare 140mm BeQuiet Silent Wings 2, 140mm...
You can use Speedfan to monitor the GPU temperature and control the PWM value of your case fans plugged into the motherboard based on GPU temperature. Otherwise you could use inline resistor adapters to slow the case fans down so the PWM range the Asus card lets you utilize are useful.
