Corsair H115i RGB Platinum Running Hot?

[RecyclopsReveng3]

I bought one of the Corsair H115i RGB Platinum AIO's a couple weeks ago. I'm running a 7700K @ 4.9GHz and it gets up to 78-80C after a session of Apex Legends. This seems a bit high to me? If I remember correctly, my old Corsair H100i V2 would cap out at around 65C with the same Overclock. A friend of mine is running the same cooler, his is just not the RGB version, but he has the same CPU and the same overclock and after a session of Apex, he said that Afterburner reports his CPU at maxing out at 67C. It really doesn't matter too much, I have an EK A240G kit coming in in the next day or two, but I'm going to post this Corsair cooler up for sale and I want to make sure it's working properly before I sell it to someone.

Did you check how’s the thermal paste spread?? Maybe is not mounted properly and not making good contact with cpu

Maybe you need to set the fan curves

I have yes. I took it apart on the second day to check it. The second application I used the "Plastic bag on the finger" trick to evenly spread it across the IHS.

I have both fans set to kick up to 90% when the temp gets above 45C

[RecyclopsReveng3]

Okay so here's something. I'm stupid. I looked in the software and the iCUE program was using the iCUE software's CPU temp reading to enable my fan curve. Now I don't know how many of you have used the iCUE software but it's temps are complete crap and way off. I set it to use my CPU's package temp as it's trigger and I've dropped 10C testing in Aida64 CPU test.

Or just connect the AIO fans to motherboard header.

Okay so I lied, my Idle temps dropped but my in game only dropped by 3C. 75C seems really high to me for an AIO.

At what fans & pump RPM ?

It looks like the fans cap out at around 1950 RPM and the pump is capping out at around 2500 RPM

75° C on CPU package in gaming with that ? Either you have some sky-high vCore on it or it's not mounted properly. Check vCore voltage and CPU package power readings in HWiNFO.

So I actually dropped the OC to 4.8 GHz. Highest core says 1.410V and a max of 44W

Ouch. That's HIGH. It should be stable at 4.8GHz and 1.25-1.30 V easy.

Ill go into BIOS then and mess with it. I have everything at auto and shit lol ill dig into it and report back in a minute

So I went into BIOS and looked around, when it's set to Auto, the base voltage is around 1.13 or something super low. I'm running OCCT right now, and it looks like it's jumping up to 1.36 and hitting 65C ish. With OCCT running, HwInfo is showing that I'm getting SUPER close to that 1.4V. I've been digging around online for the past couple of minutes and some people are saying to set the voltage to manual and run it at 1.3-1.35, others are saying that it's not good to have the CPU running at the same voltage ALL the time, especially if you're not boosting. Some people are saying to run adaptive or offset. It seems like there's not one solid all around answer lol

CPU will downvolt itself when it doesn't need that voltage. Offset might work but i have no idea if your board has this feature, if not then just try to set some voltage, 1.35V should be enough for 4.8GHz, try to lower it as far as it's still stable, it'll lower thermals and power consumption with no downsides at all.

Got it, I'll try it right now. Thanks dude. Ill let you know

Just an update for you, I knocked it down to 1.35 volts, if I ran it at 1.3 OCCT would throw up a ton of errors after about 8 minutes, HOWEVER, towards that 8 minute mark I'm hitting about 88C and working my way higher. if I run 1.25V I get error almost immediately but my temps are lower. I think I can dial it in between 1.35 and 1.30 and have it still do it's just. But the fact that it's getting to almost 90C at 1.35V seems kind of insane to me.

I'm also delidding and adding a copper IHS to the system in couple days on top of adding a new loop (EK). Hopefully my temps will be better. I really, honestly think this cooler is having some type of an issue.

Are you sure you've mounted it properly ? Because i have Corsair H115i Pro and R7 3700X, it sits at around 80° C but with ~1000 RPM on both fans and pump, now, that's 110W package power in comparison with 140-150W on your most likely but still.

Yeah last night I took it off, re-pasted and remounted and I'm still getting weird temps. The pump also started making a bit of a weird noise last night. So I'm pretty convinced this cooler has a weird issue going on.

Hmm, RMA it then, these thermals ain't right even without weird noise.

I think that what's happening is that there's a giant air bubble in the loop. When I first got it it was making a crazy trickling sound. I thought I got it out but the noise still comes back no matter what. I think they short-filled the loop and that bubble is working its way through the pump and that's why I'm getting really irregular temps and it's also what's causing the grinding noise now.

Well, some air in the loop are okay, it should migrate to the top point of the loop but that'll work only if the pump are lower than highest point of the radiator and if it's mounted on the front vertically it should probably have radiator inlet\outlet on the bottom too.

your on a 7700k it's a hot chip because intel likes to cheap out on there thermal paste the 8700k is even worse your temps look fine for a 7700k intel even said not to overclock the 7700k because it ran so hot
