Hello everyone!

On my case I only have 1 rear fan at 620 RPM, I will put one on front and on side.

Rear - Exhaust.

Front - Intake

Side - Intake

I want to know if its 100% the temperature goes down?

Thank you

If you list your computer specs including case model it will help to provide a mental image of what your rig looks like. This helps provide the best information in return for intake and exhaust recommendations.

But to try and answer the question as best as I can with what you have provided, yes, most commonly cases feature cold air intake from the front and side with exhaust in the rear and top. Adding additional fans (unless you are disrupting circulation) almost always increases case flow. Lowering temperatures.

There is very little about computers that's guaranteed except that at some point they will die. If you only have a 620 RPM rear fan though, it would be a real challenge to not improve temps by adding ANY fans. It's a safe bet.

Yes apart from the powered headers on the motherboards being able to be controlled by a variety of methods you can use a fan controller. However it is important to note that fans are designed to operate within a range of RPMs.

It looks like Asus includes AI Suite II with your rig. This software features UI to control fan speeds. Also it looks like you dont really have a lot of options here for fan placement.

Yep it will definitely help with temperature mitigation.

With the AI Suite I can put more RPM's in the fans?

The AI Suite will give you control over your fans connected to headers on your motherboard that allow those features. As for the new fans it will all depend on how you connect to them.

What make and model fan do you have? What models are you anticipating purchasing?

It will be connected to the PSU, because I only can connect 1 fan to the motherboard I think.

I will buy:

Coolermaster SickleFlow 120mm
Revoltec Air Guard 92mm

If you connect them to the PSU via a 4 pin molex or some other adapter you will get full power from them. Absent the use of a fan controller you will not be able to adjust those fans, they will always operate at max speed.

What RPM should the rear fan have?

I'm not sure what make and model it is. Depending on size and airflow rating some can move slow or fast.

depending on the scale at which it ramps up its airflow it is rated up to 1400 rpm. I'd imagine as your system gets hot the fan speeds up dramatically.

So there's no need to manual set the rear fan up?

Here's my temps:

some people set their fans to max and others leave them on scales. Honestly it is up to you. If you are not experiencing any overheating then maybe a scale is fine. Some players like to have quiet rigs and others are more interested in cooling.

My personal preference is cooling.

My personal preference is cooling too, which RPM do you recommend? I think I could have better temperatures with the new fans so, because my case only have 1 FAN which is the rear one

I would run it at full, your current flow is a bit lacking so max is best.

And when I have the front and side fan inserted? I'll keep it running at full speed?

That is really up to you. Unless you are overclocking or have loads of peripherals and hardware that needs case cooling I'd allow it to resume the auto scale. But it really is personal preference. I like the freedom to adjust the speed on my computer. Max when I am gaming and auto when I am not.
