Maximus VIII Hero and i7 6700k, cooling problem coincidence or BIOS?

[Tibblesx]

Hello,

I have been meaning to post this for the past week but I honestly though I could figure this out on my own between everything I have done. Basically, a week ago I was messing around with the 5 way optimization settings as I used it when I overclocked my system when I built it back in November. I only pushed it 7% back then as this build was quite a step up from my previous one. Before this I have never had any issue with my computer other than some ASUS software causing latency issues which I uninstalled, and some lower performance than I would have liked from World of Warcraft while trying to record using a capture card. I cannot tell if this is a coincidence or not, but I was messing around with those settings and watching videos and trying to understand the program better than I did back in November. I mindlessly left the CPU target temperature at 90 (meant to leave it off) after just playing with the sliding scale to see what the ranges were out of curiosity and moved on to check other settings. This missed my second glance to make sure I was happy with all of the settings and I told it to perform the overclock tuning.

That very next restart during the overclock tuning gave me a CPU temperature high reading and sent me to BIOS to change it, I forget what I did, but on this restart or subsequent CPU high temp error restarts just turned monitoring for my CPU temp off as it is the only way I can get to windows. Once I finally made it to windows it tried to continue with the overclock tuning I remembered the sliding scale and I am fairly certain that I left it at 90. While in BIOS and start up the temperature will rest directly at 89 degrees and really does not budge other than to drop as low as 87, and move right back to 89. It never does actually hit 90.

In an attempt to try and rectify the situation I think I tried to run the software again setting the target cpu temperature to both off again and 60 but since that the first time in this story I have yet to have it overclock successfully as it did when I built the rig. At first after this incident the temperature would reach as low as 40 once in Windows and idle, and go as high as 70 during stress testing with Prime 95 over a few hours.

Skip ahead a week and now I find myself having higher temperature readings when idle in windows ranging from 60-80 (still 89 in BIOS) and yet the cooler, its pipes, and the exhaust from the cpu cooler do not feel warm at all at any point. It is sitting at 70 right now, according to the AI Suite 3 software. The 5 way optimization tool still will not run properly and fix issues, and I have also tried reinstalling Windows completely in an attempt to fix another issue that occurred which was that the cpu after one restart would not function higher than 0.2 ghz and maybe it almost unusable. I have also tried repeatedly in rapid succession and individually hitting CMOS and loading default BIOS settings. But this only removes almost all of the overclock settings, I say almost because the BIOS will still set the ratio to 42 upon resetting and push up to 4200 MHz.

I would try uninstalling AI Suite 3, but the BIOS temperature readings of 89 still occurred before I installed the software after reinstalling Windows 10. If this is in the wrong forums, I am sorry, and I am also sorry for the wall of text. I figure I should try reseating my cooler, but nothing feels hot, as if it is actually reaching these temperatures. So could the sensor just be wrong (of course it would be strange for it to be wrong after what I did). Thank you for your time.

Edit: I should also mention I have never noticed temperatures like this before that reset, and I certainly never at any point received a CPU temp too high error on start up.

Hello Tibblesx

You're in the right place and welcome to the ROG forum.

I haven't used ai suite in a long time so I'm not too familiar with it but what you could do is install real temp 3.70 and see if there is any difference in cpu temps. Do not open AI suite.

You have a good cooler and if temps are still reading high I would suggest to uninstall ai suite III and run the ai suite III cleaner and update the bios.

If temps are still high after updating the bios then focus on your cooler.

Hi Nate,

Thanks for the quick reply there. I have uninstalled Ai Suite 3 (and everything along with it on the list there) after checking the temps with Real Temp 3.7 and used the cleaner after. I am still receiving CPU Over temp errors upon boot until I have BIOS ignore the temperatures. It will still shoot right up to 89 and sit right there and not move. These are my temperatures in Windows after allowing it to sit idle for maybe 3 minutes on my desktop. Had some issues getting the website to accept my screenshot, so while I messed around with Imgur the temperatures have dropped about another 10 degrees while resting. While still considerably high for no load whatsoever, it seems slightly better except for the fact that it really likes 89 degrees.

I have also since tried again resetting CMOS and loading default settings repeatedly after running the cleaner to make sure everything is truly gone. My BIOS does still read that it is trying to get my processor to run at 4200 MHz, but it may have always been that way, and I just overlooked it back in November. I take it the next step would be to reseat my cooler, and of course reapply thermal paste?

The default Turbo for the 6700k is 4.2GHz so it's normal what you're seeing in the BIOS. If you're running your system at stock defaults and you're still getting these high temperatures, I would recommend you check your AIO and make sure it's working.

It is not my intention to sound condescending, as I have no idea of your experience with PC building, but did you remember to remove the protective film on the back of the cooler heat transfer plate?

Hello.

When a new serie of maximus comes out on the market, you have to wait 1 year to 18 monthes to get a real, well-working, BIOS version.

I would say 8-10 monthes is the minimum to get a reliable system. Before this, you will have to use Acronis software a lot.

Hey, thanks for all of the replies. Sorry for my delayed response this week was crazy for me and I did not have a chance to do much of anything until yesterday with my computer.

Not really condescending at all, people do stupid stuff and I know a lot of people's problems are that simple. While I do not have any specific memory of removing a protective film I must have in order to wipe away the thermal paste that was on the base, and applied my own.

As far as I can tell the cooler is working fine, and again these temperatures only started after messing with the AI Suite 3 software. The temperatures have remained the same after reseating my cooler as well and reapplying new thermal paste. The temperature tends to stay around the provided screenshots no matter what kind of load I throw at it, they just simply stay relatively the same. As far as I can tell the cooler is working, I feel movement in the tubes, it appears to be powered on, there is no dust that I see. Fans are blowing cool air, I have had them blow warm air before this all happened but not lately.

It might sound really dumb, or it is just my paranoia of that one setting that I talked about setting accidentally, but everything started on that next reboot. I had never had a "CPU too hot" error on start up before the reboot after I accidentally selected 90 degrees cpu target temp. Before that I never saw my CPU past 70-75 under full load. However I uninstalled the software, and ran the software cleaner, both of which did not seem to change the CPU temps at all.

Clear your CMOS as well. Then report back your results.

[Tibblesx]

I have cleared CMOS and loaded defaults in BIOS many times before and after every step to no avail unfortunately. As far as using the Q Fan in BIOS, where is that exactly? I just did some digging when I got back and did find something that allowed me to set my pump to manual options, which had reasonable presets once under manual. This however does not seem to be helping too much. I am seeing the temperature dip down to 83 occasionally but then it will raise back up to 90ish now. This is better than it just being 87-90 though I suppose. I mean, is there an option in BIOS called cpu target temperature, just as there is in the AI Suite software? I seem to have found what would be the closest thing I think, but then also I do realize CMOS and all that would disable this if it were changed too.

Edit: looking at BIOS again the settings I have been messing with are under Q Fan Configuration, so no need to answer that first question I just forgot what it was called I guess. Long week.

Bios is reliable now, i had some stability issues too last fall(maybe partly because of aisuite 3) but recent bioses are stable with hero viii for months now. Atleast with my system.
