How to decide on a case for air cooling (warning - pics) - Page 131

post #1301 of 2110
I just tested a Slip Stream PWM like this : http://www.scythe-eu.com/en/products/fans/slip-stream-120-pwm-adjustable.html on voltage and PWM controls

Running with voltage control :
483

And same fan running with PWM control :
481

Variable range knob was set to max speed during both test runs. These seem to be quite similar to normal 1900 rpm Slip Streams that ehume tested when running on voltage control.

edit.

When range knob is set to minimum speed response to PWM control looks like this :
484

And same with voltage control :
483

So that means that at 5V this fan is somewhere between 800~1000RPM. Good to know smile.gif

By the way, I just use a Klein Nibbler to cut off the pci pillar slots but I noticed that it didn't even improve my GPU temps, so why is that?

Do you have a mid case fan? Can't remember...it's not always a guarantee temps will go down. Or perhaps it's warmer due to summer approaching?

Yes I do have a TY140 midcase fan. Well, I'm from the Philippines here and it's always hot in here especially during the summer smile.gif

Will cutting the slot pillars off supposedly affect only GPU temps?

Would this work well for cooling?

I'd need more data than that.

Cutting out your slot pillars will help if your gpu blows air into and out of the case, and if you have a goodly supply of air coming from your mid-case fan. Basically, it is something you do to to improve airflow by improving your exhaust. If your gpu already sends all of its air out the back -- as with an NVIDIA reference design, for example -- cutting out the slot pillars will not improve gpu temps. What it will do in that case is render your rig slightly quieter.

Sure.

I am using a HAF X case and I will have:

140mm front intake
230mm front intake

140mm rear intake

200mm side intake

2x200mm top exhaust

h100 push/pull, pulling air out of case
