razzeh Posted February 28, 2013 Share Posted February 28, 2013 Hello, Yesterday I've installed a new H80i. I've noticed my temperatures are pretty high. 40 degrees idle and after only 1 minute of Prime95 it went up to 70 degrees. Even my old H40 had way better results then this. I've been using Corsair link and tried to play around with the fanspeed for a bit but didn't help. Also i noticed while installing I had a loose backplate. But I'd read on this forums its normal? Ambient temperature is 20 degrees and i have a good airflow i my case. Please can someone help me to get better temperatures? Some computer specs: OS: Win 7 64 Bit Case: CM Storm Scout PSU: Corsair AX750 CPU: I7 2600K @ 3.8 ghz. GPU: MSI GTX670 PE Mainboard: MSI P67A-GD65 Link to comment Share on other sites More sharing options...
hurtmypony Posted February 28, 2013 Share Posted February 28, 2013 Looks like we posted the same issue around the same time! I am in the same boat: RealTemp reports 27-33c idle, Corsair Link reports 25 -27c. RealTemp reports 77c under load, Corsair Link rarely exceeds 60c. In Corsair Link, my H80i Temp (the liquid) shows significantly lower temps than the Corsair Link CPU Temp, sometimes the CPU temperature is almost twice that of the H80i Temp in Corsair Link. For me, it seems like a poorly-seated sink. Link to comment Share on other sites More sharing options...
nm3210 Posted February 28, 2013 Share Posted February 28, 2013 In Corsair Link, my H80i Temp (the liquid) shows significantly lower temps than the Corsair Link CPU Temp, sometimes the CPU temperature is almost twice that of the H80i Temp in Corsair Link. You expect the temperature of the entire body of liquid to match the quickly changing CPU temperature??? The coolant temp is never going to get very high unless you have the thing going for a VERY long time (and at some point you're going to reach an equilibrium temperature between the heat input of the CPU and heat dissipation of the radiator). I mean it's pretty basic thermodynamics (but that's kind of pretentious to say). With that said, depending on how much you're overclocking you could very well get the chip very hot (instantaneously). I personally overclock around 25% on my old i5-760 and see idle of 35C (CPU) 29.5C (coolant) and running Prime95 for 10+ minutes never see temps get above 63C (CPU) 35.7C (coolant). Another big factor into this is what profiles you have set up for how the fans behave when they see a bunch of heat; personally I run a custom profile within CorsairLink which turns the fans very low (875rpm) around 30C and full blast (2250rpm) around 36C. Then on top of that I have SpeedFan controlling my other fans when things get hot. So my computer is basically silent when I'm doing nothing and usually moderate when I'm doing something intensive (and yes, pretty dang loud if i'm running Prime95).

bommie Posted February 28, 2013 Share Posted February 28, 2013 i got 27 idle and 80 loaded :) Link to comment Share on other sites More sharing options...
hurtmypony Posted March 1, 2013 Share Posted March 1, 2013 You expect the temperature of the entire body of liquid to match the quickly changing CPU temperature??? No, lacking experience, I only expect the performance/experience other owners report. Regarding the discrepancy in the CPU temp and the H80i temp, I am just going off some of the already-speculated troubleshooting documented on this board with this particular cooler, such as: "The temperature difference between the cpu and the coolant in the second screenie tells me straight away it needs reseating. " in this link here: http://forum.corsair.com/v3/showthread.php?t=113741 I am not overclocking - I am using everything at stock settings. I have the H80i fans set on the default "performance", but no matter how high or how quickly the CPU Temp shoots up, or how little the H80i Temp climbs, or how long they stay there, the fans remain at a constant 1600 - 1650 RPM. The H80i Temp, which I understand monitors the liquid, has rarely breached 30c even when Prime95 and/or IBT sends the CPU temp to 70c and higher for 15-45 minutes during stress tests. So, I have fans that never change RPM, which may or may be normal for the "Performance" setting I chose, and I have a H80i temp that never climbs beyond 30c, and it is hard-put to even climb to that after 100% load for 30 minutes. Again, if this is typical behavior for an Ivy Bridge i5 3750K, and 27-32c idle and 76c under load at stock speeds is what I should expect, just let me know. And if the H80i temp report remaining at 30c or less while the CPU climbs well into mid- and high-70s for what I consider an extended period (30 mins plus?) is totally normal, I'd love some reassurance. It seems a lot of other people have more luck with this H80i than I have, which is why I suspect I seated it incorrectly. Link to comment Share on other sites More sharing options...
razzeh Posted March 1, 2013 Author Share Posted March 1, 2013 http://s22.postimage.org/vyu04o8wh/Naamloos.jpg So does my H80i need reseating? Because my H80i temp is only 23 degrees? And the loose backplate is not a problem? Or do i need some rubber washers? Thanks Link to comment Share on other sites More sharing options...
hurtmypony Posted March 1, 2013 Share Posted March 1, 2013 So does my H80i need reseating? Because my H80i temp is only 23 degrees? And the loose backplate is not a problem? Or do i need some rubber washers? Thanks Not sure, Razzeh. I am just as informed as you are regarding the H80i's standard operating temperatures and their relations to one another. Maybe everybody's H80i has such a large difference between H80i temp and CPU Temp after a consistent, 30-minute 100% load. I am only reporting what others have written, and can make no claims of accuracy for any of it. That's why I am hoping other more experienced folks can chime in and inform us.

MacNB Posted March 1, 2013 Share Posted March 1, 2013 So does my H80i need reseating? Because my H80i temp is only 23 degrees? And the loose backplate is not a problem? Or do i need some rubber washers? Thanks nm3210 makes very good points. Your H80i temp of 23degC relative to 40degC CPU seems low. Seems to mean that the pumps heatsink is not getting hotter which implies it may not be in good contact with the CPU. Run Prime95 for 15-20 minutes and see how they differ. If H80i temp does not change much, then you have your answer. Regarding the loose backplate...it's a none issue. If it's loose BEFORE you mount the pump to the CPU, that's fine but it must not be loose after tightening the thumbscrews. Link to comment Share on other sites More sharing options...
razzeh Posted March 3, 2013 Author Share Posted March 3, 2013 Thanks all. I just reseated the h80i and its all good now :biggrin: Applied new thermalpaste and mounted it really tight. (not too tight ofc). My temps are now 30 idle 50 load. Link to comment Share on other sites More sharing options...
alexanderhunter Posted May 3, 2013 Share Posted May 3, 2013 Hey Razzeh. I've been trying to figure out why my H80i temps are insanely hot too, my initial guess was that it had to be reseated, but I wanted to try easier methods first (flipping the fans from exhaust to intake, rotating the radiator, setting fan speeds to max. nothing worked, I"ll try reseating as it worked for you. would you mind sharing what thermal paste you used to reseat your H80i to your CPU? Thanks, much appreciated! Link to comment Share on other sites More sharing options...
alexanderhunter Posted May 5, 2013 Share Posted May 5, 2013 Update: So I reset the H80i and temps did improve by about 5-10 degrees. I used tunique tx-4 and applied it using the pea method in the center (I left the paste tube next to a window to let the sun loosen it up before I applied it). this allowed me to turn my fans down and now i'm idling around 35-42 (across my 6 cores) with my push/pull fans at 630 RPM for very quiet cooling. Unfortunately the H80i radiator makes some vibration noise because one of the screw holes was stripped when I got it and so it can't securely attach to my case so I have sent in an RMA request. Thanks again for the solution Razzeh. Link to comment Share on other sites More sharing options...
lazyacevw Posted May 25, 2015 Share Posted May 25, 2015 Just in case anyone is googleing this: The rubber washer addition helped my H80i. i7-3770 (x41 to x43 multiplier) Asus P8Z77-V LK Before washers, I got 79°C under Prime95 Small FFT with the H80i water temp of 30.7°C. After washers, _I got 73°C under Prime95 Small FFT with the H80i water temp of 32.6°C. The delta between the core temps and the water is a little higher than I would like but it did show improvement. nm3210 above, reports a delta of 27.3 and mine is 40.4. But, that could be because of the accuracy involved in reporting core temps. I have no idea where I got the rubber washers but they are 1.07mm thick and have an inner hole of 3mm. Next time I am in there, I might try two of the washers stacked up. Link to comment Share on other sites More sharing options...
vespa5 Posted June 5, 2015 Share Posted June 5, 2015 Do you have a snapshot of your setup? Sometimes, all it takes is a little cable management or possibly replacing that 1 fan that you didn't know that conked out, or flipping 1 fan to exhaust or intake to give you different results with any cooler (in your case, the H80i). To be honest, my personal experience with the H80i was so mixed, that I took the plunge and upgraded to an H100i and my spiking temp woes disappeared.

This makes no sense, how can the max temperature under load be lower with a higher water temperature (2 Celsius = 35.6 Fahrenheit). Link to comment Share on other sites More sharing options...
