Corsair AIO running CPU at 200 (F)

[EthanWater]

HELP! I just did a rebuild of my system into a new case, and replaced my AIO with corsair's h100i white edition, everything looks right on the dashboard as far as RPM's go, but I'm getting serious heat issues, I reseated my AIO twice, cleaning the old paste off with rubbing alcohol and reapplying with fresh paste (around a large grain of rice), screwing it down, and unscrewing it to check the spread, it all looked good. When I power everything up and open up the dash, its right back up to near 200 (f) (90+ C). 

 

• I'm running a i7-9700k at stock clocking
• evga z370 classified K mobo
• Hydro Series™ H100i RGB PLATINUM SE 240mm Liquid CPU Cooler
• Commander Pro (4 fans running to it, 2 are connected to the AIO's fan headers)
• 6 LL fans 
• 64 gb of corsair ram (sitting at around 100 F)

Attached is the export from the icue dashboard, and a screen shot of the dash. 

 

If one of you beautiful bastards helps me solve this I'll seriously paypal you some cash. If i werent already bald I'd be ripping my hair out trying to figure this out.

What's the pump RPM reporting? Do you hear sloshing within the AIO?

It’s reporting 1200 I think, the system is off atm 

[TempestCatto]

That seems normal.

 

Listen for air in the loop and make sure your hoses are routed to be as straight as possible. How is yours mounted to the case? I believe top mounted should get you the best results.

It’s front mounted because it won’t fit on top.

As previously stated, make sure for whatever reason there isn't some air in the lines or the block itself. When you turn the PC on, tint it from side to side, front to back, basically flip it all around (assuming you don't have a harddrive in it, they don't like that. If you do, unplug it form power while you try this). That can help get the air out of the lines or block and into the top of the radiator.

I’ll give it a try, would disconnecting the radiator and just shaking that around do the trick as well? Might be easier than shanking the whole case

Observations:

-Your pump ia reporting 2776 rpm which is fine for asetek and is probably spinning fine

- your coolant temperature is very low (25 c) indicating that the heat is not being passed onto the AIO efficiently

- Fans at 0 rpm on the cooler is probably the zero rpm mode when the coolant is below 40 degrees.

 

So from here i can only guess two things:

- Poor mounting of the block, i know you said it looks fine and youve done it a few times, but please post a photo of the thermal paste spread on either side of cpu and aio block

 

My good spread example

 

-incorrect temperture of the coolant reported by the aio. Touch the radiator and if it is cold to the touch then all is fine. If it is hot then the temp sensor might be busted.

[EthanWater]

the spread on the cpu looks similar to that, maybe a tiny bit less around the edges. the AIO does feel cool, but the backside of the mobo where the cpu sits is very hot, I'm going to attempt the air bubble shake this evening, and will report back.

I actually had the two fans on the AIO plugged into the commander pro and not the AIO. I've changed that since then, to no change.

Good idea, good luck.

 

Have a look here for some more of my opinions:

 

With regards to shaking, if you can do it with the AIO dismounted (provided you have either an extenral PSU or alternative cooler for the CPU). Try something like this.

 

[EthanWater]

shook the AIO radiator while it was off the case, heard the slosh at the radiator, put everything back on, and i'm still running hot

 

[EthanWater]

I sent a help ticket into Corsair about this, we'll see what happens...

This really is the level of "not removing the plastic sticker" level of hot, I think we really need more diagnostic pictures like what I mentioned above (pictures of unmunted blocks, thermal paste spread, etc).

Maby the IHS on the cpu is not flat I've heard that's a problem with 9th gen take the cpu out put it on a flat surface if it spins the IHS is not flat and you need to lap it. Just what I got from jayztwocents

Sure. I'll take pictures tonight once I'm home from work. Thanks for following along with this.

Also the corsair AIO doesn't have a plastic sticker, probably to prevent stupid shit like that from happening, they have a big hard plastic cover that clips over the mounting arms so it's impossible to put on without removing it.

I've never heard of that issue happening. has it been reported on i7-9700k's?

No on 9900k's but they probably use the same IHS

It is a "thing" but its only for those seeking to improve upon normal temperatures, unflat IHS/cooler is not going to be the reason you are at 105 degrees celcious.

Yea, I assume it isn't going to be the reason, besides thermal paste would even out the minute variance in flatness anyway. I'm going to take pictures, and probably a video of the build with the AIO being pulled off and wiring to give reference tonight, and hopefully there is something simple im missing, and everyone can call me dumb, and we can go on our marry way.

Just a thought, turn the whole computer upside down and run it, or take the radiator off and make sure the hoses are lower then the rest of the unit. I wonder if the hoses being at the top are not drawing water like maybe not a full charge of water.

Isn't it recommended that the hoses be at the top of a radiator when it's vertically mounted so the pump doesn't have to work against gravity? I'll give it a try either way this evening. At this point, it can't hurt...

[Tallguy64]

Honestly, i am just starting to dip my toes in water cooling, but from other experiences fish tanks and automotive work both hoses at the top are generally a no no. I just put one of these in my desktop build too. Since these have no reservoir and if the unit was low on coolant i could see it sucking air and not cooling properly with both hoses on top. If there was air in their due to insulating properties of air i could see the temp of the cooler showing much lower.  At least its the only theory i got.

If you are mounting an AIO cooler vertically you want the hoses on top(higher) if you mount it the other way it puts a decent amount of strain on the pump. If you are mounting horizontally in the case it doesn't matter. Fish tanks filtration systems and cars cooling are completely different from an AIO CPU cooler.
