H100I GTX Fan Speed Maxing

Hey

 

Ive had a H100I installed for a few months now, One thing that has been bugging me however is the fan speeds and noises.

 

I run my h100i on quiet mode in the link app as i like abit of silence, However when under load my CPU reaches the temps of 45 degrees C the fan speeds will go to max until its cooled below this point. In the link software the quiet mode setting doesnt show the fan curve as ever being able to go past 60% which i would prefer as i dont believe the fans going to 100% does much good in the pull configuration i have.

 

It has done this from the start, the default fans were very noisey so i replaced them with noctua PPC fans that can max out at 3000 rpm, Athou these are very noisey to at max rpm they sound clean.

 

Basically i just want to stop the fans going at 100% at 45 degrees as i believe this is pretty low anyway

 

Any ideas?

As above. You will likely need to use a custom curve with fans that have a different RPM range than the original fans. However, I am curious why the fans are going to 100% at your current temperatures. The fans change speed based on the water temperature inside the H100i (H100i Temperature or H100i Cooler Temp), not CPU temperature. The normal 100% fan speed temperature is around 40C water temp. I would be a little abnormal to have a load CPU temp of 45 and corresponding water temp of 40C. Do you have 30C+ room temperatures? Do you have a large amount of GPU heat in that situation? Is it really running 3000 rpm on quiet mode or more like 2000?

Thanks for the reply.

 

It useually idles at around 32 degrees temperatures (The cooler Temps). I have two 980TI''s running and one of them is always around 60 degrees because of the amount of monitors i run.

 

I never thought the idles were much of a problem, i bought my pc from PC specialist, The first one they built me had great many issues and the CPU would on load run at 65 degrees which i didnt really know was too high until they built me a new one using stock fans and it only caps out at 45.

 

Your probably right tho, its probably my water temps hitting 40 degrees causing it and not the CPU, Is it much of a problem having a 5 degree difference between CPU and Water block temps? I believed my temps could be a little higher then most reported 5930ks because i run 3000mhz ram and had to change the base clock speed to 125mhz aswell as turn off speed step to prevent any bugs.

 

RPM on quiet mode ranges from 1400 RPM to 1800 before it hits then 40/45 threshold and goes to 2800.

I should probably just start asking people if they have a Ti any time a high water temperature question pops up. It is routinely the answer.

 

So, with two Ti's, your water temp does make sense and so does the unusual 40 water/45 CPU idle temps. The delta between those two is fine and suggests the pump and flow are normal. If your voltage isn't stepping down on idle, that would figure as well.

 

The Quiet Mode setting is still bothering me a little. The different RPM range is expected with a different RPM range fan. However, it really should not shoot up to max. My old H80i would do this every now and then, but I was able to "fix it" by selecting a fixed RPM or % and then setting it back to Quiet Mode. I haven't used LINK in more than a year and not V.4.xx at all. Perhaps some protocols were changed. Either way, you absolutely will want to keep using a custom fan curve to keep the fans in check. Just pick an RPM you can stand and tie that to your expected water temps while gaming. Dial it back down from there to 40C. The really high fan speed won't become necessary until your CPU temps start getting high at load.

 

On a side note, watch out for the 125 strap and SLI. It does cause some issues for people with complex set-ups. Your hardware isn't listed, although I am starting to suspect an Asus board. You should be able to get 3000 on the 100 BCLK unless perhaps you are running 32GB+ or 8 modules. I won't pretend that was an overnight process for me either, but I do think you will be able to improve in time.

45 degrees C is about 113 F which is cool for the cpu. I had a similar issue with my system and H100i and I just solved it. First I complained about the Corsair H100i stock fans revving up to 100% during boot (The Jet Roar) and I solved it by disconnecting them from CorsairLink and plugging them into my mother board so they are now being monitored and controlled by my MSi motherboard Command Center during boot, opposed to CorsairLink which does not kick in till after post. My second complaint was that my Corsair H100i stock fans were revving up for no apparent reason when using windows 10 for general web surfing. I reinstalled windows 10 (erased the entire disk, no windows reset for me) but that did not solve the issue. I was considering RMAing the H100i back to Corsair (But..I don't want to max out my CC) so I got the idea to put more thermal paste on the cpu since I applied very little when I reinstalled the H100i when I changed my mobo. Because most people here where saying less is more. I used to less to be on the safe side. Adding slightly more thermal paste solved the issue , no more loud fan roars (The Neighbors were actually complaining) and the cpu running at 93 -120 F and H100i about 88 F steady !! -- as reported by both CorsairLink & MSi Command Center. And nice and very quiet !! So there is hope for the H100i !!
