Stastic Pressure Fans or NOT? I Think NOT An Absolute even with Radiator

Hello,

I have installed the Corsair H100i Liquid Cooling system. I have a Corsair 600T computer case that has a large size grill on the top of the case that allows me to mount the H100i radiator on the underside of the grill (so inside the unit) and the two 120mm static pressure fans are mounted to the grill on the outside of the case and then there is a separate detachable top grill plate that conceals that 120mm fans. I hope I explained this setup well enough.

What I want to do is to replace the two static pressure fans with two regular Airflow Fans. Specifically, the NZXT FZ-120mm Blue LED Airflow Fan.

Here's the link to the Amazon page for additional information:
http://www.amazon.com/Technologies-RF-FZ120-U1-FZ-120mm-Airflow-Cooling/dp/B007WR0EP0/ref=sr_1_1?s=pc&ie=UTF8&qid=1366507757&sr=1-1&keywords=nzxt+blue+fan

Why? Simply because I want a blue LED light glow from underneath the top grill which is something that the static pressure fans cannot do. I understand that static pressure fans are able to push/pull more air through the radiator then a traditional 120mm computer case fan.

So, I bought the two Corsair static pressure 120mm fans over two Antec Computer Case Fans with Blue LED because I was told in this forum that I should use pressure fans with a radiator system because it requires more air and, as I understand it, only the static pressure fans are designed to effectively push/pull air more air through a radiator.

Now, some details that I think should be known before someone squashes the whole idea of replacing my static pressure fans because I want my computer to glow blue on the top and still provide adequate air flow through the radiator.

I also need to cite something that might influence whether or not I could or should be able to replace the static pressure fans. I purchased more memory (16GB) and a stronger CPU (4.6GHz) and a good MB (Asus P8Z77 V-Pro) and the liquid cooling system (H100i) because I wanted a really fast, responsive computer. I am still working on it some issues with internal drives, etc., but this new build is up and running. I am also using a SSD as my primary drive, so between all of these components I have a fast computer. I can totally multi-task and have a bunch of applications and browsers open and running and the computer is great. The thing is that I don't play games or do video-editing. The most task intensive program I use is Photoshop.

The Asus AI Suite II monitors all the different temperatures and controls the fans speeds and no matter how much I have been doing on the computer, the temperature of the CPU or the MB has never even increased above 30 degrees. It is an efficient system and not one that is taxed too much.

Ultimately, I do understand that static pressure would always be the preferably choice with a liquid cooling system with a radiator. But, does my current configuration and use of it still demand that I use static pressure fans or do I have some wiggle room or maybe more than wiggle room? I would appreciate some feedback on this issue.



 
Solution
Static pressure optimized fans are only really needed with higher FPI (Fins per Inch) and thicker radiators, the H100i is neither. You should be fine to replace the fans. Also there are blue LED static pressure fans out there, look up the Silverstone AP121.
Though why not just get some dedicated lighting like an NZXT Hue or Bitfenix Alchemy LED cable? Youl get a much better effect than you will with fan LED's.

Yep - static pressure fans are only a concern for actual watercooling; the h100i has pretty low static pressure needs.

That being said, led fans really aren't that impressive - like manofchalk said, the bitfenix alchemy cables are just about the end-all be-all of case lighting tech right now, and you already have the fans... replacing them with lower quality fans seems silly when you've got a better option that won't reduce performance.

Hi ManofChalk, Thank you for your valuable feedback on my issue. I did look into the Silverstone AP121 Fan and it is definitely a superior fan to the NZXT Computer Case Fan w Blue LED that I originally asked about. The only downside with the Silverstone is that it does not glow strongly. I watched a YouTube video on it and also read a number of Amazon customer reviews that too said the glow was low. I then investigated the NZXT Hue Controller that you recommended as a possible alternative to replacing my fans. I was impressed with how it worked. I again watched a YouTube video on how it worked, how it glowed, and how you can control the lights w the Control Panel. I am going to go with the NZXT Hue Controller that I found on Amazon for less than $30.00, and that seems a very reasonable price, plus I am an Amazon Prime member so the item will be delivered to me within two business days. Perhaps I will follow up in a week with how pleased or not I am with the NZXT Hue. I cannot do it this week because I have to write an major essay paper but after that is done than I will install it. Thanks again for your insightful advice.

Also, thank you DarkSable for your feedback as well.
