Need help with GPU mod

[MoistyMcMoistface]

 

-Overwatch is pretty much the only game I play and is easy on the CPU, but is enough to warm up my RX480, not that I am even pushing my card hard at all; I'm hardly even giving it a 75%  load with overwatch, but it is enough to get the freaking thing screaming like your daughter waking on you going at it with your sister-in-law.   

-CPU and case temps are always low, the CPU & case fans never have to ramp high enough for me to even notice them

- 95% of my computer's acoustic output is from the freaking graphic card! My computer would be literally silent if it was not for that meat hook abortion of a reference cooler. 

 

Ok so my 3 questions are:

Most important question: 

-Can the fan header on the RX480 board even SUPPORT a full sized 120mm LED(just one colour) case fan without damaging the rest of the GPU components? (due to power specs of the controller?) I know the header it's self is not the same dimensions as a case fan header but I saw some adapters for 5$ on amazon.ca from mini 4 pin to full sized. I would really appreciate an answer from someone who has actually seen this done <3.

-If it will, what does this mean for the Wattmaster software? Will it freak out? Can I still set the fan curb as if it was normal?

Why I can't plug the 120mm GPU fan into my mobo:

- I already looked into what people who buy them kraken G10 water cooler to GPU adapter do with there ancillary 90mm fans; they plug them into the Mobo: this works for them as the fan is only for the SMC's of the GC and not the ONLY source of cooling for the card. Hooking up my 120mm fan idea to my mobo wont work at all, Usually my case fans always run at 15% becasue wherever the thermistor on my mobo is; it is far af from the GPU because it always reads near ambient, and my i56600 is so freaking power efficient and the games I play are so CPU independent it never gets hot enough for the mobo to ramp the case fans. 

 

Question 2:

-What fan type should I get, I'm thinking a SP optimized  fan because it will have to push the air through the venturi? Or is that not a good idea and AF fans are better?

- If I go with the SP fans, I think that I would get 2 the same and use one for the case. I would do this because I don't want the LED colour to be off between 2 fans of different models. Is using a SP fan to cool my case the end of the world or is it insignificant? 

 

Question 3:

- Am I the only one who actually thinks this will work? I mean it seems like it should work, a larger 120mm fan pushing more air, and becasue it is going through a venturi; rather quickly? I'm doing this for the sound and not the performance. I am trying to match the performance of the reference fan while reducing the acoustic signature.  Or am I stupid and wasting my time. 

--------

 

Overall I think the price of this will be cheap, much cheaper than a VGA aftermarket cooler: 

 

Plastic clipboard: $1.50 ( for the hard cardboard to make the venturi shroud)

120mm fan filter: $8.50 (I already have 1, need another)

Tape, glue, and plywood : Free 

2X 120mm SP fans: $13 each (https://www.newegg.ca/Product/Product.aspx?Item=N82E16835181067&cm_re=120mm_fan_pressure-_-35-181-067-_-Product)

 

~$5 shipping  

 

Grand total: $41 + tax 

(And I get to keep them fans after I'm done as well as the filter, since I plan on using my 480 till she's obsolte damaging the shroud is no biggie)

So at the end its more like 16 bucks in cost. 

 

Nearest VGA cooler: 70$

You could simply add in a couple of extra intake fans and call it done to get positive air pressure. It wouldn't require modding the GPU to have it's own ducted system.

I'm not trying to get positive air I am trying to make the card more quite. Do you know anything about the card fan header thoug?

With a blower design that is going to be hard to do as slowing down the fan or lessening the flow of the current fan will affect performance. If you get an adapter you can hookup a regular fan to the header on the GPU as long as the new rated fan doesn't exceed the rating of the old fan you take off. That will ensure that the header isn't overloaded.

But it cost more money than grade A hooker. What I'm doing here will only cost like 16 bucks If you don't count the 2 fans

The fan intakes from the top, not the back. My blower cards never had trouble breather, regardless of the case.
