New fans?

[Dkozak]

So my local Pc store has these "Lepa BOL.quiet" Fans

Specs: 

• 8-18 dB
• 69.2 - 138.4 m³/h
• 40.72 - 81.45 cfm

So I would assume these are Static Pressure fans looking at the cfm, correct me if I'm wrong.

I'm not sure which ones I'm going to take since there is a PWM version (€ 17.99) and a 3-pin version (€ 14.99). Does it make a big difference?

I have the following fan setup: 

1: 3 NZXT stock fans (FNv2 ) INTAKE

2: 1 Ghetto mounted Cooler Master Sickleflow 120 (keeps my GPU about 5-7°C cooler) dunno if I'm going to keep it 

3: First slot (1/3): Cooler Master Seidon 120V rev 2 in Push Pull (Push = stock cooler | Pull = Cooler Master sickleflow) EXHAUST

    Last slot (3/3): Aerocool 140mm INTAKE

4: NZXT stock fan 140mm EXHAUST

 

But I was thinking of moving my rad to the back (4) and put it there in push pull with 2 of the LEPA Fans and keeping the aerocool 140mm as intake to push some fresh air into the pushing fan at the back.

What are your thoughts about it?

Why new fans?

Why new fans?

Well the fans that I have now are getting old and I'm starting to hear some noise from them (the one in pull config) and the stock fan on the rad (push) isn't that good in my opinion. 

I'm also thinking of moving the rad to the back to improve some airflow (I hope).

Have you tried lowering their fan speeds? What are your load temps?

[Dkozak]

Idle 33°C on cpu and 43°C on gpu

Load 45-55 ish °C on cpu and max 65°C on gpu

Depends on the application, these temps were when I tested 3dmark

What cpu and graphics card do you have?

Have you tried lowering fan speeds?

My bad, forgot to quote . 

I have a i7 4790K running at stock speeds with turbo boost enabled and a sapphire HD 7950 boost.

Those temps are very low. You're fine up to 90c at load for either of those.

No I haven't tried it yet. Not home atm but now I know that the temps are fine I'm satisfied . Thanks for all the help.
