First water cooled rig is getting too hot - Page 6

post #51 of 75
OP, can you post a picture of what the back side of motherboard/CPU socket looks like with the waterblock installed?

Does it actually look like this in the video?

I will when I get home later today.
But yes, it does look like that. Just the 4 screws.

You can see how it gets mounted here: https://www.youtube.com/watch?v=KAxloa-W7q0
I guess my mistake was not tightening it enough, because in the manual it explicitely said not to overtighten and compress the springs "too much". Which is a really ****ty description in my opinion.

I will reapply the paste (less this time^^) and tighten the **** out of the cooler mount.
If that doesn't help I guess I'll have to replace it. I'm really unhappy with the Phobya parts. Was trying to save a few bucks on this already expensive project. Might have been a mistake.
The manual for the block is kinda bad, the reservoir came completely without one and the cpu block feels kinda cheap in general.

That is a bad idea ahahah, remount the waterblock and tight the screws in a Cross pattern using the same amount of pressure on every screw. start with 1 turn on every screw then 1/2 turn ect, leave it a bit loose, turn on the PC run some cpu stress test. Keep tighten it by 1/4 turn on every screw until the temps doesn't change


Sorry for the bad english ... redface.gif

Yes, there's literally just a tiny washer on the back side of the motherboard, to hold all that pressure. That just looks like bad waterblock design to me.

People saying too much tim remind me of the people whom say re install Windows every time there is a problem. And low and behold it never fixes the issue. Make sure you have the correct orientation for the jet plate. If you didn't clean the rads you may have something clogged in the channels. Start with the simple things and just eliminate one at a time.

You mean how the the TIM looks after i remove the block?



That's how it looks now, haven't started the PC again yet.

I noticed that the screws for the cooler start turning when I tighten the nuts(?) at some point, I haven't used a screw driver to hold them in place since the manual explicitely said not to overtighten them. But maybe it's not tight enough?

I will upload more pics of the interios tomorrow, they are in my dropbox and the web version is super slow atm. And the local copy is on the PC that I just took apart wink.gif
wayyyyyy too much paste

*This* is way too much: (Click to show)

OP had just been a little bit generous in his TIM application.

And keep in mind he was specifically asked to do test mount and check TIM spread. What he posted shows TIM spread nicely.

That spread does look suspicious though. Now realizing there's no backplate that might not be a coincidence at all.

He squeezed like, literally half a tube on. After applying the heatsink with proper pressure though the excess squeezed out the sides and left a perfect layer between the IHS and heatsink and thermals were within a margin of error from the "proper" amount. Now obviously you shouldn't do this on purpose, as that excess that gets squeezed out the sides makes a big mess and if you put WAY too much it can start filling up around the socket which isn't good obviously, but a little more than needed isn't going to cause major issues. And according to this site, application method doesn't really matter much either. As long as even pressure is applied thermals come out within a margin of error. In terms of coverage and air pockets though, the X method and Pea method (as is generally recommended and most commonly used) seem to be the best.

I believe you are referring to Jayz2cents. Here's the video. It's a video card but the same rules apply. No such thing as 'too much" as long as your within reason.

That picture is the extreme example of too much. In most cases a paper thin layer of tim is all that's needed.

Okay, I'm back smile.gif

Photo of the mainboard's backside:



So I tried switching the inlet outlet ports on the cpu block and orientation, as expected that made it worse (not by much, but noticable)

I re-fastened the screws to the motherboard, reapplied TIM (less than before) but the block back on and fastened the nuts more than during my first try.
Sadly, there is really no discernible difference. I fastened the nuts during stress testing as much as I dared (the springs are now completely compressed)


After 5 minutes of 100% load during prime95 temp are at ~75C with peaks of 80C
Idling at 30C-50C as before.
