brownie4420 Posted November 20, 2018 Share Posted November 20, 2018 Hello! So as the title says over the past week or so ive been having issues with my CPU temperatures. First of all some back story. I have had this same CPU / board / cooler setup for 3 years during this time the paste has never been reapplied nor has the cooler been reseated. About a 3 months ago I noticed my temperatures were much higher than when I first build my PC (around 75C at 100% load, originally were around 60C or so) I made a mental note to keep check on it and replace the thermal paste at some point. so this leads us to last week, I checked the temps again and was sitting around 85C instantly under full load. So I ordered some thermal grizzly paste, cleaned my CPU / Cooler with Isopropyl, applied the new paste nice and thinly covering the whole CPU. Put everything back together and my temps were much better back down to about 65C under full load....this lasted about a day. The next day when I booted my PC temps had shot back to even higher temps than before this time around 95C full load, after only 1 minutes of Intel stress test. So I assumed bad contact or bad paste application, took everything off again and the paste was nicely spread across the CPU, so I put everything back together same issue. It seems random sometimes it will be sitting 80C full load and then I reboot and repeat and its back to 95C - 100C. After some Google I came across some threads regarding loose backplates etc., which mine certainly is but everything tightens up nicely when the pump is in place and its ran without issue for nearly three years. Few things I think it could be- -Faulty Pump -Still bad contact (possibly due to loose backplate) -issue with my CPU? Sorry for the long post, but some help would be appreciated. EDIT - Forgot to mention: -idle temps are around 45C-50C -ambient temperature is around 24C Link to comment Share on other sites More sharing options...
c-attack Posted November 20, 2018 Share Posted November 20, 2018 We need to know what's happening with the coolant temperature (H100i GTX Temp) in iCUE/Link. That is the key to differentiating a cooler issue from everything else. At 24C room temp, you idle H110i GTX Temp should be around 27-30C, with a +5-6C for a CPU only stress test. Not uncommon to see +10C when gaming because of the additional GPU waste heat adding to the coolant temp. If your coolant temp is sitting around the 40-45C mark at the desktop, there is a problem.

Sure, so idle on desktop it sits on 39c-40c and flucuates between them. Double checked my ambient its actually 22c. Coolant temp does seem high, I recall it being much lower when I first installed it maybe low 30s / high 20s. Link to comment Share on other sites More sharing options...
c-attack Posted November 21, 2018 Share Posted November 21, 2018 Sure, so idle on desktop it sits on 39c-40c and flucuates between them. Presumably if you apply any type of load, the coolant temp goes up rapidly and then takes a long time to come back down (it should be slow up, moderate going down). Another thing to check is how the exhaust from the radiator feels on your hand. At 40C coolant, the exhaust is also 40C. That should feel quite warm. If it's cold or cool, you know the heat is not being transported to the fins. Pending confirmation, it seems like you have a flow restriction developing. You can try taking the cooler out and shaking it, but that is really a short term measure with no guarantee of success or much scientific merit. Use the support ticket system to contact Corsair to start the RMA process or start looking for a replacement (or both). Link to comment Share on other sites More sharing options...
brownie4420 Posted November 21, 2018 Author Share Posted November 21, 2018 Yeah, coolant temp is extremely quick to rise and very slow to come down. Exhaust from the rad is very cool (cold if anything). I tried taking it out of the case giving it a good shake and putting everything back together and its still the same unfortunately. Looks like I will have to start an RMA. Will they want me to send the current cooler back before sending me another one? just I will buy a cheap coolermaster evo or something in the meantime. Also when feeling the tubes coming from the pump one is pretty warm and the other is cold. Not sure if this is normal Link to comment Share on other sites More sharing options...

I think this is fairly conclusive and you need to move forward. Yes, you are required to send the cooler back, then they ship you a new model. Depending on where you live, this can create up to 14 days of down time. I know that doesn't work for me. They usually have an option to do an "Advance RMA", which is the typical credit card hold on the value of new cooler, they ship the new immediately, then you ship the old back within xx days (30?). That at least cuts the time in half. However, your options are pretty limited as to usage right now, so might want to choose from the below. 1) As you suggested, buy the cheap air cooler bolt on until this is sorted. Just watch out for complex air towers that are going to be a tight fit. I did this once with a Dark Rock Pro 3 as an alternative. I can take out my Corsair coolers, change the fans, re-paste and re-attach in 15 minutes. That air tower was a 4 hour install requiring me to strip the case nearly bare. It has never gone back on since. Keep an eye toward ease of installation. 2) As discussed above, air towers are a pain. These days I keep a water cooler back up instead. Now that thing has a limited shelf life and 3-5 years down the line, I will likely need to dump regardless. However, you are likely to receive a Corsair H115i back from Corsair. This is the mid-cycle name change to the H110i GTX, albeit with one or two firmware level changes in your favor. This is definitely not my favorite cooler of all time. If you are not overly happy with what you have now, find something new and get installed. Keep the brand new sealed H115i as a back-up, use it in another system, or find another avenue of disposal. Regardless, I think everyone should have a back up cooler on hand these days, especially if you need to stay operational. Link to comment Share on other sites More sharing options...
brownie4420 Posted November 21, 2018 Author Share Posted November 21, 2018 Thanks for the help matey. Put an Express RMA In and bought a Coolermaster 212 for now as a backup and rolled back my OC to stock in the meantime. Hopefully whatever Corsair sends me works wonders like the h110i did originally. Link to comment Share on other sites More sharing options...
