Antixs Posted June 2, 2018 Share Posted June 2, 2018 Hi, Just installed new motherboard today and I am getting random CPU temp spikes really high temps when idle. https://drive.google.com/open?id=1ijAU7LV2PNcq90bzc4THBqRaLowU0vds CPU- i7-8700k Motherboard: rog strix z370-e gaming Cooler h150i pro I have reapplied thermal paste 4 times still same, I have had CPU temp spike into 90c when playing path of exile for 5 mins Link to comment Share on other sites More sharing options...
Zotty Posted June 2, 2018 Share Posted June 2, 2018 Have you got an AirCooler to be able to see if it does it with that too? Link to comment Share on other sites More sharing options...
c-attack Posted June 2, 2018 Share Posted June 2, 2018 I can't load/watch that video. However, the first troubleshooting step should be to isolate CPU temp from coolant temp (H150i Temp). When you are sitting on the desktop, what is the H150i Temp in Link or iCUE? What is the approximate room temperature? Most people have a resting coolant temp of +4-7C above their room temperature. What is the CPU package temp when sitting at the desktop? The cores never really stop moving, but you should see a package temp within a few degrees of the coolant temp, once the start-up cycle finishes and things settle down. What happened to H150i Temp when you were gaming? It should have only gone up 1-2C in just a few minutes. Most likely you need to do some BIOS tweaking of the CPU behavior for a 8700K. This is true of all Kaby/Coffee Lake chips, no matter what cooler you strap on. With MCE on in the BIOS, you could easily pull 1.40v playing a game on otherwise default settings. Can you see the peak Vcore value in Link? Link to comment Share on other sites More sharing options...

Can you see the peak Vcore value in Link? My idle temps are all over the place within a second it can jump up from 40 to 62 and back to 45 then 50+ all within a couple of seconds. Games can push it to 80+ within 5 mins I always stop scared of it getting higher. Link to comment Share on other sites More sharing options...
c-attack Posted June 2, 2018 Share Posted June 2, 2018 Unfortunately, Kaby/Coffee Lake CPUs are so inherently jumpy, it's difficult to tell a bad cooler mount from normal behavior at the default settings. The very first thing you should do is figure out how much Vcore is being applied to the CPU. This value should pop up in Link and a maximum recorded value will appear in the graphing section. I am expecting a higher than needed value and that would explain the temps. Another way to do this is to see if coolant temp rises. If it doesn't move at all, then you probably have bad contact between the cold plate and CPU. Use a light CPU stress test (like Intel XTU) and run it for 5 minutes. Coolant temp should go about +5C with medium fan speed. I would prefer to get the Vcore sorted first. Link to comment Share on other sites More sharing options...

I am using CUE not sure to see Vcore graph, I have watched it for a bit it constantly changes 0.70- 1.12 1.30 0.67 0,98 1.15 all about the same within seconds nothing over 1.31 The Pump temp does go up slowly when the stress test it moved up from 30c to 35c within a minute.

c-attack Posted June 6, 2018 Share Posted June 6, 2018 I think we need to look at your BIOS settings. If you have not already read it, google up the Asus Kaby Lake Overclock Guide from the Asus Edge site. Yes, I know that was for z270, but it is the same. Can you tell your basic settings now? All side fault? MCE on or off? Auto voltage? Or a specific adaptive value? Link to comment Share on other sites More sharing options...
JiCO Posted June 6, 2018 Share Posted June 6, 2018 Check your CPU Usage in Task Manager, iCUE is sitting up to 20% at times with the May 5th update. Link to comment Share on other sites More sharing options...
JiCO Posted June 6, 2018 Share Posted June 6, 2018 iCUE also shows that there's a Firmware Update for the H150i Pro, but it fails to update every time. Link to comment Share on other sites More sharing options...
c-attack Posted June 6, 2018 Share Posted June 6, 2018 Check your CPU Usage in Task Manager, iCUE is sitting up to 20% at times with the May 5th update. This issue predates the iCUE version causing this for some people. CPU spikes always will be program, voltage, or physical contact related in origin. The cooler itself can’t cause it. Fortunately, I think we are looking at general Coffee Lake, Asus Enhannced sassiness, which is cureable. Link to comment Share on other sites More sharing options...
sharmanov Posted June 11, 2018 Share Posted June 11, 2018 Having same issue with Ryzen 1700 on Krait Gaming x370 board as if the pump isn't pumping right or not enough coolant in radiator Link to comment Share on other sites More sharing options...
DevBiker Posted June 11, 2018 Share Posted June 11, 2018 Having same issue with Ryzen 1700 on Krait Gaming x370 board as if the pump isn't pumping right or not enough coolant in radiator That's pretty unclear. How about you start a new thread where you describe your specific issue/concern in detail. Some things we'd be interested in would be: - Exactly what temps are you seeing? - What are you doing when you see those temps? - What is the temperature of the coolant? - How quickly does the coolant temperature increase/decrease?

SO the coolant temps range from 30C-40C depending on cpu load and what happens is while my CPU is idling around 2-5% the package (my ryzen 1700) will spike up to 45C-50C and immediately go back down to 35C-32C and will keeps repeating it every 20-30 seconds. the coolant temps take dont spike up nearly as fast and stay pretty consistent. My Ryzen was OC'd to 4.0GHz 1.39v i down-clocked it to 3.9GHz 1.35v just to be safe. I mean the temps are definitely much better then stock cooler and i wasnt even able to hit 4GHz OC before the H150i but was wondering it normal for my CPU temps to spike up like that while idling?

That sounds pretty normal. All of the current gen processors have spiky temps like that. What's your max coolant temp under load, especially mixed (CPU/GPU) load? (you may have to play some games to find out). Link to comment Share on other sites More sharing options...

(you may have to play some games to find out). when i do stress thing through cpu-z it gets up to 70C max in cpu side, didnt check the coolant temps under load Link to comment Share on other sites More sharing options...
saltedham Posted June 15, 2018 Share Posted June 15, 2018 dumb question but did you take off the plastic off the part that goes on top of the cpu? Link to comment Share on other sites More sharing options...

You'll only get lower temps by delidding. Link to comment Share on other sites More sharing options...
Antixs Posted June 17, 2018 Author Share Posted June 17, 2018 Just update I fixed my temp by replacing the backplate that comes with AIO it felt like it was fitted correctly but turned out it was like a millimeter to lose. Once I placed it with a custom one temps have been normal nothing over 60c while gaming in far cry 5 :D Thanks for the Help DevBiker and c-attack appreciated It still spikes up and down really fast when ideal but like Dev said that is settings in bios which I will need to sort out in future :D Link to comment Share on other sites More sharing options...
