Ask GN 59: Does CLC Pump Speed Matter? Auto OC or No?

By Published October 02, 2017 at 3:07 pm

This is our first Ask GN in a few weeks, with the gap between being filled with travel and other projects (as has been indicated by recent uploads, many of those include case reviews). For this week’s Ask GN, we’re addressing questions of how important CLC pump speed is, auto-overclocking and its annoyances, pump whine elimination, personal case preferences, and open loop cooler limitations.

As always, the timestamps have been dropped below the video.



01:39 – madwolfa: “Maybe this is more appropriate here: How important is the CLC pump speed at all? I've played with it yesterday and the delta is like 1-2C at most (with the pump speed between 50% and 100%). Rad fan speed seemed to impact temps much more.”

06:13 - Vithor Leal: “Hey Steve! Great channel and great unique video content! Keep it up! I have a question for the next #AskGN : Why don't we have hardware that's capable of determining it's own limits for overclocking? Like, why can't motherboards and graphics cards (specially AIB partners') auto-tune themselves to their maximum provided some parameters (like fan speed or CPU/GPU temps and voltages). In an ideal world, you'd plugin any CPU to a compatible socket and the same with a GPU and have a button on UEFI that's labeled: "OC FOR ME". IF this exists already, why isn't more widespread? Thanks! Hope you see this!”

12:48 – madwolfa: “Hi Steve! To disassemble a 1080 Ti Hybrid for a PWM adapter install, is it necessary to remove the backplate, and basically do what you did in the tear down video? Is it possible to just remove the top cover?”

14:42 - Red_M: “@Steve Burke Could you maybe look at doing case round ups? I personally have a HAFX and I'm curious to know what you'd look at in a case, for personal systems”

17:40 - KRIL89: “I asked this last week but probably after you made this video So I think is a good question and prob. would need to ask AMD for this So HBM on my Vega 64 gets pretty hot, i've seen it get up around 85c. What is a safe temperature for it run at for an extended period of time? I also seem to have a but when I overclock the memory and under clock the card (for mining when I'm not gaming) in that I lose fan control and it part of the reason it over heats.”

19:02 – Eidelweiss: “At what point do you saturate a custom water loop? I read some stuff that beyond a certain amount of rad space for your parts, extra radiator space isn't going to do jack squat for you. What determines that limit?”

Please leave questions on the video comments section for next week!

Steve Burke

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
