Fans for Silverstone RL07 case

Franksi · 4 Aug 2019 at 13:12

After getting a parts list together for my partners son he's chosen the above case with a red lighting theme.

I was thinking of replacing the exhaust 140mm fan with:

and then adding 2 of these as front intake fans:

Any thoughts or better suggestions for a red LED setup?

Thanks in advance

The linked fans have very low pressure, meaning they can't overcome grill and filter resistance.

We don't need rear exhaust fans, just high pressure front intake fans.

I would use at least 2x 140mm high pressure rated front intakes, 3x 140mm if they will fit. CPU cooler wth 140mm fan/s needs a little more 1x 140mm intake fan airflow because of gril & filter resistance, and 2x-3x fanned GPU needs almost 2x 140mm intake fans of airflow. Removing all PCIe back slot covers greatly increases rear vent area exhaust airflow and thus better front to back airflow around GPU giving it lower temps and letting less of it's heated air move up into airflow to CPU cooler.

thanks for this - will take a look for something suitable

so ditch the 120s and get 3 of the 140s? is the model spec'd any good?

2x 140mm fans move about same amount of air as 3x 120mm fans of similar design. No, they are not really much good. While 1200rpm is fine 99% of the time, there are times we need more .. like when we have summer temps like we have had.

Sorry, I can't suggest any RGB fans because I don't use any. I would look for PWM controlled fans with max speed of 1300-1600rpm and pressure rating of 1.5mm H2O or higher. Variable voltage is okay, I just prefer PWM because it does not generate any heat at lower speeds like variable voltage does .. but both work fine.

Link below is to basic guide to case airflow might be of interst, just open spoiler:

how about these?

Specs look okay, but I've never used or seen any good reviews. Just searched for again and come up with no reviews doing A/B testing with other fans. Sorry, no idea.

i think what we are saying here is "light the case another way and get fans that other people know work"

Basically what Franksi said. Phanteks has their RGB 'Halos' but they cost more than fans do. Lower cost option is use RBG stips. There are many available, some with a remote to control for repeating pattern, color and brightness, etc.

Arctic P14 is pressure oriented bang for the buck fan.

With price difference between those and usual marketing hype/fashion fans you would fast get some light strip etc.

In case of that case I think it's better to have also exhaust fan.
It really doesn't have that much of exhaust holes.
So would be better to make sure that there's no warm air floating around CPU...
Left there by graphics card whose cooler is designed to fail to give a damn about case airflow.

Probably true .. it's back vent grill is very restictive blocking about 60-65% of vent area. Below link to Silverstone has data of airflow through those vents with grills vs open airflow vent. The bottom round hole vent looks similar and only flows about 29% of air a open vent would.

Removing PCIe back covers and anything else that can be removed will definitely improve front to back airflow around GPU thus lowering air movent of heated GPU air up to CPU thus lowering both CPU and GPU temps.

I have removed bottom and back venting, used lower resistance filters on some cases and of couses always use good pressure rated fans in all cases. The difference is amazing. Below is extensively modified Define R2.
