System temp test results 1 vs 2 exhaust fans

Hey LTT,

 

so i'm not sure if people normally post any results here but here goes.

 

Before you complain to me, i have no clue on how to make fancy graphs etc so you going to have to read this :P 

 

Hardware:

CPU Used: i7 4790k @4.7GHz at 1.37V ( Delidded with Coollaboratory Liquid Ultra on the DIE ) and MX-4 on the IHS. All this is cooled by a Noctua NH-D14.

GPU Used: ASUS GeForce GTX 1080 Ti Strix OC 11GB ( out of the box settings all default core clocks and fan curve )

Case Used:Fractal Define S with 3X Thermaltake Riing 14 140mm fans in the front of the case - then we have 3X Thermaltake Riing 12 120mm fans (2 of them are on the NH-D14 cooler and one as exhaust fan.(all Thermaltake fans are on 100% for this test)

 

when i build this system i wanted to have only one exhaust fan so i could keep the top of the Define S closed of for noise,

I had an extra Noctua NF-A14 PWM laying around and figured i might as well use it but i wanted to know if it was worth it.

 

i ran these 3 tests in order back to back: Superposition benchmark 4K Optimized > aids64 cpu+fpu 2min > GTA V single player benchmark.

Room temp in all these tests were 23.5C

 

in the results below it will be 1 v 2 exhaust fan(s) chart 1 is with one exhaust fan (Thermaltake Riing 12) / chart 2 will be with the extra added Noctua NF-A14 @850rpm in the top of the case.

 

--------------------------------------------------------------------------

 

Test 1 with one exhaust fan:

GPU

max temp : 72C
max fan speed: 48% = 1741 RPM
 

CPU
min/max C1 - 31 / 86 Delta= 62.5
min/max C2 - 29 / 91 Delta= 67.5
min/max C3 - 33 / 90 Delta= 66.5
min/max C4 - 30 / 84 Delta= 60.5

 

gtaV scores: 36.6 / 141.8 = 89.2 (min/max/avg)
superposition 4K benchmark score:9247

Test 2 with two exhaust fans:

GPU

max temp : 69C
max fan speed: 42% = 1549 RPM
 

CPU
min/max C1 - 29 / 83 Delta= 59.5
min/max C2 - 27 / 88 Delta= 64.5
min/max C3 - 31 / 87 Delta= 63.5
min/max C4 - 29 / 81 Delta= 57.5

 

gtaV scores: 47 / 154.6 = 100.8 (min/max/avg)
superposition 4K benchmark scores: 9267

 

Conclusion and thoughts

 

CPU temps went down by 3C

GPU temp  went down by 3C

GPU noise output was very noticeable, 6% = 200RPM difference is allot imo 

 

now where i'm a little confused is the Superposition benchmark VS GTA V benchmark results,

as you can see the results are no different in the Superposition banchmark but in GTA V we went up in FPS by Allot for just adding one exhaust fan,

our min FPS went up by 9FPS our max FPS went up by 13fps and our average FPS went up by 11FPS

as a note i ran all tests 3 times and all 3 times the 2 exhaust fan setup did better in GTA V.

the GPU ran at 1961MHz in all tests so no faster speeds because of the lower temps.

 

hopefully one day this will help someone,

 

thx for reading i guess :D

here's a run from the GTA V benchmark.

top side is with the 1 exhaust fan

bottom side is with 2 exhaust fans

i guess my second exhaust fan has some magical powers
