Gelid uv fans

[SmokeDankTrees]

I'm building a new gaming pc and I'm going with an all black scheme, but I'd like to add some color by adding some blue uv fans by Gelid. (I will add a few uv cold cathodes to bring out the color in the fans )

My build (I haven't purchased any of the items yet):
cpu: intel i5 2500k
cpu cooler: thermalright silver arrow
mobo: GIGABYTE GA-Z68X-UD4-B3
gpu: sapphire radeon 6950
case: corsair 650d
memory: corsair vengeance 8gb
psu: corsair 850ax

This is what I plan to do:
-I want to add 2x 140mm UV Blue Gelid fans on top of my corsair 650d. (They will be exhausting air)
-I will add 1x 120mm UV Blue Gelid fan on the rear of my 650d (exhausting air)
-I will also replace the stock fans on my thermalright silver arrow and add another 2x 140mm UV Blue Gelid fans. (push/pull method)
-I will leave the stock 200mm fan on my 650d that is in the front of my case. (this will be the only air intake I have, which is really my only option).

My concerns:
-By removing the stock fans on the thermalright silver arrow and adding 2x gilded fans will I Change any performance of the cpu cooler significantly?

What I'm trying to achieve from all these fans are a nice contrast in color between the all black scheme and uv blue fans. What I am worried about is if I will have a significant amount of heat increase on my cpu by replacing the thermalright silver arrow stock fans with the blue uv gilded fans.

We all had to learn at some point.

It's always nice to mod your case with lighting if that's what you like.
But i would have a hard time replacing the TR TY-140 PWM mm fans. http://www.xbitlabs.com/articles/coolers/display/140mm-fan-roundup.html
I would find a use for them elsewhere in your case.
You would also have no problem selling them = i wouldn't.
That being said at least your choice of Gelid fans is a very solid one.
The 140mm Gelids aren't PWM which isn't a big deal and are 900rpm which is similiar to the TY-140mm 900~1300RPM.
