CPU/H115i running too hot

[TIGERSHARK27]

My CPU and cooler are running too hot, and it's gradually gotten worse since its initial purchase (nearly 2 years ago). I clean out the filters and dust often enough, and I had the the PC put together professionally (after I had a bad experience with a dead motherboard) so I'm pretty confident the thermal paste was applied correctly and the heatsink and backplate are seated properly, although I plan to check again. I'm certain the correct bracket was used.

 

The PC is less than 2 years old, so I don't think the thermal paste would have worn through, not to mention my CPU temps don't jump crazy fast upon load, but they do steadily rise to high temperatures.

 

Idle Temperatures are very high for an AIO CPU cooler. Room temperature is almost always 20° or less. https://i.imgur.com/clzboO7.png

 

Other than the "Motherboard 5" temperature being high, all the other temperatures seem fine to me. This is also with a custom fan curve, although it's comparable to Balanced/Performance presets. The Quiet preset idles closer to 60°C on the CPU.

 

Assassin's Creed: Origins (my most CPU-intensive game) usually has my CPU Package peaking at 80° C, usually averaging 72-78°C.

 

As you can see from the picture I linked, the water (or temp at the pump) temperature is idling at around 38°C, with 20°C room temperature, and peaks above 50° as can be seen in the linked photo.

 

I'm guessing there is blockage or another issue with the pump, but I don't personally have any experience with this. The radiator is mounted at the top, as exhaust. All my PC specs are in my profile.

 

Let me know if I missed providing any important info. Any help and suggestions are much appreciated (I plan on bringing my PC in but wanted to get some expert opinions here first!) Thanks for any help!

 

EDIT: Also, unfortunately the i7-5820k doesn't come with a stock CPU cooler, so I don't have another to test, although at a Hyper 212 EVO's price point, perhaps it's worth buying even just for testing...

It certainly appears to be a blockage. Normal idle coolant temp runs +4-7C over room temps with CPU only loads at +6C beyond that (at 100% load). You have a massive 28C delta and your idle is drastically too high with maximum pump and high fan speeds. Start a support ticket through the Link at the top of the page. When detailing the problem, be sure to mention the coolant temp continues to climb, even at the desktop, that very large 28C coolant range, and the large difference in coolant temperature when changing between Balanced and Performance Mode on the pump. That should not happen.

 

This is pretty conclusive. You are going to be without for a while and likely cannot stay down for this long. You can ask for the Express RMA from Corsair where they send you a new one on credit card charge hold, then you ship the old back. This is not always available and you have to specifically ask for it. Even then, it would probably be another 7-10 days before you get relief. I do think everyone needs a backup cooler. You can get an inexpensive air cooler to tide you over. These do not fall apart sitting in the box and longevity is high. The downside is they can be very difficult to install or impossible if you have high profile RAM. I eventually gave way to both and keep a back up 280mm as well. It may be worth your while to look at a new cooler of whatever shape and design you like, and then use the replacement cooler as a backup, in another system, or something else of value.

Go ahead and get that support ticket created and provide a copy of the receipt and our technical support team will make sure the issue gets addressed.

Has this been solved? I am experiencing a very similar problem, only my temperatures are even higher (90 - 94°C when playing newer games). I have an i7 6850K.

 

I noticed this very recently, and yesterday I cleaned the whole case, cleaned the radiator, cleaned the fans, and replaced the thermal paste. I played CoD:MW and Battlefield 1 today and the temperatures are going right up to the 88 - 93°C range. My idle temp is 50 - 53°C.

 

I checked to see if there were any weird tasks running in the background, but everything looked normal. This computer is now almost 4 years old. When I first got this system from iBUYPOWER I remember noticing how low the temperatures were, usually only getting to about 65°C when gaming.

 

I'm seeing some talk about liquid evaporation, or maybe a blockage of some sort. Is this a known problem with the H115i?

Hi to all

having the same issue here. Got my H115i in 2016 and few days ago it started to jump with temps.

Here is a screenshot of iCue dashboard and I am just having in background Google Chrome and Word Document opened.

 

 

H115i is mounted on top of my Corsair Graphite 780t with two Corsair SP140 fans on my radiator. Air flow and exhaust fan are standard fans that are included in Corsair Graphite 780t.

 

I am still on stock thermal paste btw. I am going to try with Thermal Grizzly Kryonaut (as soon as it gets delivered) to change thermal paste. (Not quite sure if the thermal paste is going to help)

 

Hope someone can help me to solve this.

 

Thanks in advance

Corsair support contacted me and sent a warranty RMA form.

 

I paid a deposit, they sent me a new one, and I sent back the defective one. If you don't want to pay a deposit, you can just send back the defective one and they'll send a new one once they receive it. I use my PC for work and didn't want to wait, so I paid the deposit.

 

The new one was fun to install, it works great, and I couldn't be happier!

49-50C coolant temperature (H115i Temp) is pretty much at the limit. It's possible to get that high after load GPU load sessions (like gaming) by heating up the case. However, if you cold boot up in the morning and then can watch the coolant go from room temp to 40C+ in a matter of 5-10 minutes, something is wrong.

 

Other clear indicators are if you heat up, but can never come down in coolant temp. This is a strong indicator heat is not being transported to the radiator at the rate is should. Best to make this kind of assessment when the PC has been off for a while.

 

Go ahead and contact Corsair Support now. You can add details to the ticket later if needed.

[Daniel77]

Hey NightCrawlerBRC and c-attack you are the best. Thank you for your respond.

I got ticket number and now I am waiting (or should I contact Corsair Support more)?

 

I am going to make screenshots after cold boot and on every 5 min.

 

Thanks again.

[Daniel77]

This is how it looks like after cold boot

 

 

H115i is now 40C and CPU 45-50C

 

What could I check more? Any advices?

[Daniel77]

 

Hope this also can help in some way.

i wonder why your CPU idles at over 10% utilization. the thing is constantly working which doesn't help.

Maybe after 4 years it ended up cooking the stock paste, but the cooler wouldn't be that hot, only the CPU.

Definitely looks like a pump/flow issue

[c-attack]

I agree. +14C coolant rise is like strong sustained load. The only other thing that can do this is if the fans/radiator are preventing from expelling their heat. So if you just got a new case and it has solid front door and a dust filter pressed up again the fans, it's going to have a temperature cost.

 

That said, you mentioned this was new behavior and that is more indicative of a building flow problem. If you are Southern Hemisphere and heading into Summer, you do need to be mindful of environment changes. On the other hand, if the room is now colder than it was two months ago, the coolant should be as well.

Hey to all and thank you guys

 

Outside tempereature is like 5C (Winter) and get's lower than that ofcourse. Room about 16-20C.

 

 

About Pump, I think I found the problem so to say. I don't know how healthy for my pump is to be whole time on extreme performance but that helped me -10 degree to get. Pump was on quiet and it couldn't get lower than 40C.

I would say it looks better now....

[c-attack]

Actually that puts the final nail in the coffin that you have a flow problem. In a healthy AIO cooler, the pump speed is largely irrelevant and definitely is at idle. I could never get more than a 1C difference at max extended load between low/high on my 280mm cooler with my 5820 and 5930K. This is true for most users and the short travel distance and generally low restrictive block makes pump speed a non-issue.

 

When we see these GTX/v2 coolers start to clog up, the Quiet pump speed becomes really difficult and results are like what you are experiencing. The blockage is choking the flow. Going up to extreme is better at getting coolant through, but that won't last forever and it's not supposed to work that way. Eventually, the extreme isn't going to work either. Make sure you mention the coolant temp drops 8-10C when you switch from Quiet to Extreme. That is a clear indicator of a flow problem.

Thank you a lot. I really appreciate it.
