Is my H100i Crazy?

[scrapland]

Hello!

I would like to express my problem with the Corsair H100i liquid cooling. I have doubts about its proper functioning and, consequently, the noise it produces.

The thing is that as soon as I turn on the computer, the fans of the device go to 100% (reactor mode noise - 2600 RPM) and after a few seconds, they stabilize at a pleasant 1100 RPM that is quite bearable. Could someone tell me if this is normal?

Moreover, when testing with the Corsair Link software, I see that the H100i responds perfectly to different types of configurations and profiles (quiet, standard, Average, Fixed, etc...). So far, everything is correct.

The problem arises when I start playing (let's say, pushing the processor). After a few seconds, the fans go back to 100% for a moment until they gradually return to their resting state. After a while, they go back to 100% repeating the process described above and so on. It is VERY ANNOYING.

This would make sense if the processor got very hot and the cooling acted according to the established profile to keep the temperature in check, but no, monitoring the temperature of the micro is usually between 40 and 50 degrees, quite stable.

The most annoying thing is that if I configure the fan revolutions as FIXED, for example at 1500 RPM, it doesn't listen to me once I start playing. In short, it skips the configuration assigned through Corsair Link.

Please, could someone with the same cooling system tell me if this is normal? Any clue about what is happening?

I have the latest version of Consair link installed (2.3.4816), the most recent firmware (1.0.5). My motherboard is an ASUS P9X79 DELUXE and my processor is an Intel i7 3930K 3.2Ghz. My operating system is Windows 8 64 bits.

I would greatly appreciate any help!

The noise at the beginning is normal.

Where do you have the cooling connected? To the motherboard? Or to the power supply?

To Both… I think. Although it wouldn't hurt to review it. :ugly:

To both?
If you want to control the speed of the fans, you will have to connect the fans to the board, and the pump to the power supply so that it does not regulate automatically, since the pump should always run at the same speed.

From what I have been able to read, the H100i's management software is causing some problems, so I recommend that you try connecting the fans to the motherboard, to a connector that you can configure in BIOS, that is not the CPU_FAN, which is where you have to connect the pump.

I think I explained myself wrong. There are two connectors coming out of the pump, one to connect it to the power supply, and another connector, a 3-pin one, to plug it into a fan connector on the board.

Apart from that, there's the USB that goes from the pump to the motherboard as well, supposedly to control the fan speed. Which it does, yes, except when I start playing games and they go full blast by god's grace

Best regards!

I think the best and most reliable thing you can do is what fassou told you.
Regular from the bios.

Two cables come out of the pump, one is for power (SATA) and the other you have to connect to the CPU_FAN, so that if the pump fails one day, the board can turn off the computer before it gets damaged.

On the other hand, the fans have the usual three-pin connector, and these are the ones we tell you to connect to the board, in a fan connector that has BIOS management.

Regarding the software, it seems that V1 works much better and has more options, but it fails when saving the profiles, while V2 is barely useful for monitoring the operation.

Salu2!

Thanks to everyone for the responses! The thing is that yesterday I started to investigate in depth and… the problem is with the power supply! It's a Corsair HX1050, and when the computer works with some load it goes into reactor mode (unbearable). RMA to the side... I hope it's a defect of the particular power supply and that it's not the model itself, which is that noisy. It would be a disaster.

I'm sorry for the confusion, I never thought that such a scandal would be caused by the power supply. Thanks again for your time.
