Cooling the Kaby Lake i7-7700k

Isn't the VCCIO the voltage for the Memory controller and DMI the Direct Media interface (or something like that) It is the connection or communication between the Northbridge and Southbridge, I think.

Sounds right, this is from the Kaby thread on OCN

PCIE Lanes:
First let's be clear about what Skylake brought to the table. With Skylake there were 16+4 PCIE lanes. 16 of them are direct to the CPU and can get used for graphics cards. The extra 4 could be used by motherboard vendors however they want, but in practice allowed for a x4 PCIE SSD to run. Typically this was run with a PCIE NVMe SSD like the 950 Pro. Those 4 extra lanes are connected via the Direct Memory Interface (DMI) and could not be used for graphics cards. It runs at PCIE 3.0 speeds, allowing for up to 4 GB/s, but with overhead the figure might be around 3.5 GB/s. DMI lanes have higher latency than direct PCIE lanes but the differences should be minor.

With Kaby Lake we have an extra 4 lanes through the DMI, bringing us to 16+8 lanes. It is important to note that the extra 4 PCIE lanes through the DMI we get with Kaby Lake compared to Kaby Lake does not increase the amount of data that can pass through to the DMI. It is still ~3.5 GB/s. Those extra lanes simply allow for better connectivity (like having multiple 950 Pros). Esoteric setups involving strange RAID setups and such will not be covered in this thread.

Ya the only thing I use AI Suite for is to manage my case fan speeds, which I rarely change. But it`s nice to be able to on the fly :)

Hi Brian, not heard from you in ages. Yes I use AI Suite for my fan profiles and use the overclocking functions a lot. I think its a really good piece of software with plenty more potential.

Well guys, I appreciate everyone's help. I wanted to post an update on this thread, because I found the source of the problem. It's a real noob mistake, to be honest.

I was using an ASUS guide on overclocking, when I discovered that my AIO pump was not configured in Q-Fan in BIOS. After configuring it and running Q-Fan's Optimize, my system is staying in the low to mid 30's when idle! I've also uninstalled AI Suite, and I am managing voltages entirely through BIOS now.

I really want to thank everyone for helping me out. I've learned quite a bit through this whole thing!

Derp.

Glad you got it sorted
