And here I am with an AIO that has only recently proved that it can be made to handle a 4.7GHz 4790K (it can handle 8GHz as well, but it hovers around 80oC, and 4.7GHz fully stable at 1.25V is very nice already).
These have been my temps with use ranging from youtube all the way up to 2x 1080p (DSR) heavily modded Skyrim (computer on the left-the plastic shell was pissing me off, so it got torn off):
Its the main reason I went with water cooling. Although just stripping the case down dropped the temperatures of the motherboard and GTX 970 drastically.
