Need HELP With Fan Configuration

[zion319]

Hello, I am having a 4670k and GTX 760 and I am doing push&pull AIO liquid cooling.

 

When I play CSGO, my CPU tends to be a little hotter than my video card. So, one of my fans in push&pull runs 2.2k rpm while the other one only runs 1.4k rpm. I am wondering how can I spread it evenly or this is the nature of push&pull configuration?

Are they the exact same fan? They need to be running at the same speed or airflow will be compromised and your fans, damaged.

I think that you have them in different fan headers, if they are same model. Fans need to be in same connector either with Y-splitter or using CPU_FAN and CPU_OPT headers which will run at same speed.

Yes. They are the same model. I bought the CoolerMasterSeidon 120XL and it had 2 fans inside. I did use the Y-splitter because I remember the MOBO had no more fan header for me to plug in. I am using Gig N97Z WIFI. 

 

Maybe I plugged into the wrong place? To be honest, I didnt know where to plug my fan in when I was installing. I simply plugged into the one I think it is and boom, both fans worked. After awhile then only I realized they are not in the same speed in gaming mode.

Okay, so. I have 2 header fans. one is called SYS_FAN while the other one called CPU_FAN. I plugged my Y-spliter on COU_FAN and my SeidonXL on SYS_FAN. Right now, I am switching one to the other, result still the same.

 

Also, i am wondering, since i am using liquid cooling, why there is still a 4pin header on my seidon?

How do you know that they aren't running at same speed when you are using Y-splitter? Since they should show as single fan in any monitoring software. Anyway if they are still running at different speeds, one or both might be broken.

Oke let's start with the basics. Do you have all the fans on one splitter on the CPU_FAN header?

I am using CPUID HWminotor and under my MOBO section, there are FANIN0 and FANNIN1 under FANS section. These 2 are running different speed. So I resume both of my fans are running different speed. am i wrong? >.<

Ok. All together, I have 3 4pins header, 1 from the seidonXL and the other 2 from 2 fans. I used the Y-splitter to connect 2 fans. Then I plug the Y-splitter on SYS_FAN and the seidonXL on CPU_FAN. is that correct? 

 

Thanks in advance!

I think I know what the problem is. You installed it correctly as Coolermaster recommends, SeidonXL on CPU_FAN and fans on SYS_FAN so don't worry about that. The CPU_FAN header is giving you the RPM of the pump, nothing more. The SYS_FAN is giving you the RPM of the fans and PWM motherboard headers usually only read the RPM of one fan. So connected with the Y-splitter and provided you're using the two stock fans the 120XL comes with, they should be spinning at the same RPM. So everything should be alright unless you're visibly and/or audibly noticing that one fan is spinning slower than the other. See if you can find out which reading (FANIN0 or FANIN1) is giving you the fan RPM and that's the RPM your fans are spinning at.

 

The stock fans on the 120XL run at 2.400 RPM max so the 2.200 RPM is probably your fans.

 

Hope this helped. What's your CPU temp under load?

@Shaqo_Wyn pretty much explained and I could say same after this post of yours. FANIN0 is what is in CPU_FAN header, FANIN is your SYS_FAN. I have renamed these in my monitoring and you can do same. It clears bit what you can expect.

Oh I see. Now I understand. Thanks alot.

 

My CPU temp is 28 idle and about 38 in gaming. I didn't really go for stress test such as prime95 yet because I don't have time for that yet. I play dota2 and CSGO most of the time. When I play dota2, my CPU is about 35 and my GPU is about 40. But what makes me curious is when I play CSGO. The CPU goes up to about 45-50(i know its pretty normal) and both of my fans running at 2200 rpm. Due to its loudness, at that moment I thought maybe my fans werent running at same speed, that's why the fans turn so hard. Now i know that its not.

Thanks bro. I really appreciated.
