Delta Fans any good for Radiators?

[iamdarkyoshi]

I have some Delta fans from some old dell thingies. we have all seen these computers and their absurd fans:

 

My question is if they are any good for radiators noise/performance wise? They are 4 pin fans so I know I can use PWM from the GPU and CPU headers unlike the no-name fans I currently have, which are 3 pin.

I've heard that they are extremely loud.

when they are running at 3,900 RPM of course they are loud!

Fans out of those Optiplex towers aren't good for anything other than burning. Seriously, please don't try and use them for anything. They don't even use the standard 3/4 pin fan connector, so you'd need adapters or some soldering to get them to work.

I have already put new standard 4 pole connectors on them and a dedicated power supply plug so they dont blow up the motherboard.

Even then, we have about 100 of these towers second hand at school and we use them to teach students who don't really know what's inside a computer, well, what is inside a computer. I don't recall them being delta fans though, or spinning very fast for that matter.

Perhaps they had different models. I know the ones that I got mine out of had a blue mount inside them and an ABSOLUTELY FREAKING MASSIVE aluminum heatsink to keep the pentium 4/D under control.

wait, it was a black mount with blue plastic bits elsewhere in the case. Guess they used up the world's supply of green plastic.

there are tri bladed Deltas that Screamed. they Put out massive pressure and airflow. but they were incredibly loud like 45 to 50Dba

I used them on my Peltier PC way back in 2004. had 4 in a 92x4 setup. they fit perfectly on my Ford Heater core. I could warm my room with that Rig.

these are a 120MM version. 9.2 MM of static pressure.
