jlaporte Posted June 16, 2014 Share Posted June 16, 2014 Hello, My name is Jeremy, I build a rig over a year ago and I'm learning to overclock but I'm running unto a strange issue with temperature. I have an I7 3770k (kept the lead on) sabertooth z77 for motherboard and a corsair H100i for cooling (fan in pull configuration) After a year of overclocking with not so great results I decided to restart from the ground up and to do things properly. My test were done without any overclocking Bios all reset to factory settings. I'm very surprise because as soon as I run prime95 my processor temp will jump in about 3 seconds to the high 90C according to Coretemp and Corsair Link but on the Asus Thermal Radar the temperature is 20C lower than the one indicated by the two others. I let Prime95 run for over 12 hours and Coretemp gave me basically constant temps over 100C hitting 105C quite regularly but never crashing while Thermal Radar was always 20C lower so in the mid 80C. As soon as I stop Prime 95 the temperature lower quite quickly as well and then about agree all across the 3 software. I never hear much of my H100i (except for the cooling fans) so I was wondering if it was working. The radiator remained pretty cool to the touch but one pipe leading to the pump is warm and the other cold so I believe the H100i is working correctly. Any idea why my temp jump so fast up and down and why there seems to be a difference of 20C on high PCU load between all temp monitoring software and Asus while there is no difference in idle.. I believe Asus is correct because I don't see why my processor would reach 105C with a H100i under default settings? Thank you for reading and any help you can provide.

Conners Posted June 16, 2014 Share Posted June 16, 2014 I don't know anything about the Z77 sabertooth. I do have a 3770K processor though. Could you please point me to a document about your bios configuration? Using just P95 and getting those high of temps are crazy. Do you manually set your vcore or auto?

jlaporte Posted June 17, 2014 Author Share Posted June 17, 2014 The numbers I gave you are just the one with stock setup no overclock whatsoever. I just wanted to run a test before I tried to overclock to make sure everything is fine. My computer is perfectly stable but I'm just very surprised at the temperatures differences, and why it's running that high (and running fine at those high temp) I'm wondering if my H100i doesn't work properly because I never hear the pump and the radiator stay cool even with those temps but one pipe is warm and the other cold so I would think the pump is working somehow.

jameyscott Posted June 20, 2014 Share Posted June 20, 2014 If you are experiencing that high of temperatures not overclocked there might to be two issues. One, incorrect installation of the H100i which would just be not tightening down the screws properly. The other possible issue is that the pump is not hooked up or is not working. If you put your fingers on the pump, you should feel it vibrating. If not, that's your problem because it isn't pumping the water through. If it is working, then the problem is improper installation. Hopefully we can get your issue solved so you can get to overclocking! Also, I personally don't recommend using Pirme95 because it is not something your computer will ever see under real world load, and if you go by the temps you are getting you won't be getting the max you can out of your chip. I personally recommend x264 because it's what you can see when you computer is under a reasonable load and will be game stable and rendering stable. I've done it on both of my systems and never see any BSOD or any issue while in game! To each their own though, if prime stable is what you want, then go for it!

jlaporte Posted June 20, 2014 Author Share Posted June 20, 2014 Thank you for your answer. I will try to tighten the pump and see if it's help. The pump doesn't seem to vibrate much (I believe the vibration are more from other fans in the case than the pump itself) but if the pump is not working why do I still have one pipe warm an the other cold?

Conners Posted June 20, 2014 Share Posted June 20, 2014 I suppose a person could remove the 24 pin connector from the motherboard along with the 8 pin connector, if you have one, that way the MB will be dead. You could also remove the connectors to any fans you don't want on. Then do the paper clip test to turn the PSU on. Of course you'll want to leave the H100I hooked up to the molex. Test it that way for any life... Link to comment Share on other sites More sharing options...

My H110 was never like this. The temps shouldn't be extremely different on each side because the water temperature should normalize. So it is either a dead pump or a dead fan header if it is plugged into one. Link to comment Share on other sites More sharing options...
HackManSD Posted June 23, 2014 Share Posted June 23, 2014 My H110 was never like this. The temps shouldn't be extremely different on each side because the water temperature should normalize. So it is either a dead pump or a dead fan header if it is plugged into one. I haven't had this either, I have used many different H units, and couldn't feel a difference in the tubes. I did have an H100i pump stop working and cause high temps at stock frequencies before. If you can't tell that the pump is working properly, it might be a good idea to use a stock Intel cooler to test. If it gets "normal" temps with the replacement, that pump is done. If you don't need the "i" features, try the H105...its already helped me tame a couple 4770's. Link to comment Share on other sites More sharing options...
