Fan headers and temps for a Corsair liquid cooler

[martward]

Hi all,

 

I just installed my new CPU cooler, a Corsair H75 2018. Being a good little boy and reading the manual I connected the pump to the CPU fan header and the two fans to a system fan header. I noticed it was making a ton of noise, so I went into the bios and set a fan curve for the fans (not the pump). This solved the noise and made the system significantly more silent. However I saw that my motherboard has two CPU fan headers. I was wondering whether it makes sense to plug the pump in to CPU_1 fan header and the two fans through a splitter on the CPU_2 fan header, or whether I should keep my set-up as is.

 

I also saw that my temperatures are very good for cores 2-4, around 20-21 C on idle, but is way higher on core 1, around 28 C on idle. 28 C is of course no problem but does this mean that the thermal paste may not have been properly distributed? I used pre-applied thermal paste.

 

Thanks

This is negligible, the higher tier cores are more likely to be higher anyway due to the fact that they're first on the pecking order of what the computer needs to do.

 

I could be wrong here, but as long as your paste was properly spread out, it shouldn't matter because all the cores are in the middle of the die anyway.
