It might be fine, but in doing so you are creating the opportunity to easily lift up a corner. So, while it may do no direct harm, if you're going to twist the block, you should most certainly use two hands and be very careful about it.

Also, it's really not necessary.

So after trying the spread, pea size, and grain of rice size no twisting, both the pea size and rice size so far have been the same identical temps, 68c. A lot better than the 70c the spread method gave me.

After investigating around a bit I think I stumbled upon why I am getting 68c at 4.2ghz. The fans I am using are these, Xigmatek Crystal Blue 120. There max RPM is 1500, and ~60cfm. So they are not the best fans I could be using.

Then..


As you can see from the photo, my tubing is on top. So when the hot air leaves the rad, it rises right up to the tubing, heating the cool water right back up again. And my tubing runs across my MSI 570 Twin III, which is an open air cooler. All the hot air gets vented everywhere. Even when its at idle, my 570 temps are ~41c, so it still venting some hot air which rises right up to the tubing, heating it up some more.

So what do you guys think about this?

i honestly think it's your vcore for 4.2ghz.
let me guess you put something in like 1.31 volts in bios cause ur cpuz reads it at 1.304 on load. you shouldn't need that much for 4.2ghz.. thas the volts (1.31) i run on 4.5ghz..

also, can't you just mount your h60 on the back of the case instead of front like that. it looks like your really stretching the tubes.. just my 2 cent

I'm running 1.3v's because that's what my motherboard had it automatically set to. I could drop it down. Any recommendations on what I should drop it down to?

I can't mount it on the back. My back exhaust port is 92mm.

might not make that much of a difference in temp but try something like 1.28 or somehwere around there. also fans do make a big difference in radiators so u may want to pick up some new fans that pushes more static pressure.
there was a guy in ocn for sale/wanted section that was selling ap 15 and ap 14s. not sure if he still has it.

in all honesty though i dont think 68c is that high with that vcore. thats the temps i get with 30c ambient running prime blend..

I have a 4.2ghz OC that's prime blend stable @ 1.250 vcore. Might could go lower than that.. haven't tried. But that's a good baseline anyway.

Weird. I did one run of IBT on Very High and got 95.56 GFlops.

68c is not high for that clock using IBT at all. I bet in a blend test it doesn't get over 65 or so max. Besides, 68 is perfectly fine.

It's not?

Then how was I getting 70c with my dinky little A50 at 4.8? Is my computer just magic? With an H100 now, my temps average under 50c. 70c for an H60 at 4.2 is not at all good. And, as I said, it is safe, but so is 90c. Doesn't mean it's good.

I just lowered its Vcore to 1.25v. I'll run Intel Burn Test for 8 runs and see how temps and stability plays out.
