temps on 13900k

[neufuse Veteran]

So I built a new system i9-13900k and used a Corsair H100i, the temps seem way high, sitting idle the package temp is 31C but will spike to 45C quickly during small loads, but run prime95 and the package temp goes up to 99C! This seems way hot, I just used the stock thermal compound on the cooler since I had to wait for some new artic silver, but this cooler should even with the stock thermal compound cool better than that right? I did read some people also saying that 90s is "normal" but my AIO rad doesn't even get warm under this load, which also seems odd

99C on Prime95 load? While that is a little high, I wouldn't worry about it. As you won't probably use the CPU in that way. EVER.

Are you sure everything is working, as the pump, cooling fans on the radiators, etc?

Also, try running some high CPU intensive normal programs, and see what your temps are like. Photoshop for example. That will give us a better idea.

I wouldn't say ever in my case, I do a lot of high CPU usage tasks, I can run at 100% for hours on end doing engineering simulations. all the fans are running at max speed, I dont know how to tell for sure if the pump is running but the rad is not warming up

Just a couple of quick things (I'm at work).

That is a hot and power hungry chip (over 300 watts when boosted) being cooled by a 240mm rad.

HWInfo (or similar) is your friend when checking things like pump RPM, fan RPM, watts, etc.

Is your pump connected properly, is it set to run full speed in the BIOS (or is it set to a fan curve?)

You should feel warmth coming from the rad/tubing.

How does the system react, not to synthetic benchmarks, but to your actual work?

When you get new thermal compound, check the old spread for uniformity.

Etc 

Wouldn't necessarily be alarmed at the Prime temps unless the chip is throttling tremendously.  Same with the 31 to 45 "spike" ... just hard to give an opinion of that.

In other words...I would just monitor temps throughout your "engineering simulations" ... and other normal workloads.

To add to what Jim said, if you put your hand on top of the CPU heatsink, you should feel the pump working. If not, you may have a defective cooling system. (It happens)

Did you just notice this? Or has it been running like this for a few months? Is the CPU overclocked at all?

I just put this together yesterday, this is just the first burn-in test of it, the pump has no vibration to it, but then my old corsair pump on my other system I can't feel it either, but in that case the rad is warm

yeah i know the up to 45 spike is normal for this chip, outside of stress testing it's fine, but it does throttle back from 5ghzish to 3.7ghz after a minute of 90+C, no the tubes aren't even warm... the sensor for the RPM in the pump claims its running so it must be at least picking up that pump RPM sense, starting to wonder about the contact between the heat plate and the CPU cap

Oh, yesterday, OK.

Are you sure you have the correct pins connected to your motherboard? The SATA power and the fan header (for pump)? Might want to check connection, too. If not done already.

yeah, the single wire fan header is connected to the CPU fan header like it says, the SATA header from the pump harness is connected, and the USB-C cable from the harness is connected to the pump, which is the only connection to the pump wire wise, and the LEDS on the pump are lit up so its at least getting power, also the two fans on the rad are running and do ramp up and down, although they do seem to stay running high for minutes after the CPU package temp drops back down to the 30s like it's still trying to cool something or thinks it needs to?

[neufuse Veteran]

so just curious about it, took the cooler and fan off and weighed it to compare to what it apparently is suppose to weigh... its about 45 grams lighter then what their specs say, I'm guessing there's not enough coolant/water in it and it has an air bubble....

[Jim K Global Moderator]

If your weight measurement is correct ... that is a ~ 1/4 cup fluid (I was curious and did a measurement on my little cooking scale).  I couldn't find what the weight of that unit should be.  Is the H110 old?  Is it reused from a previous build (and how did it perform on that one?)

[Brandon H Supervisor]

think you found your culprit there then if there's not enough liquid in the line. If it's a new cooler I'd see about RMA'ing it

was brand new, or at least it SHOULD be brand new

so I finally got my artic silver... swapped out the cooler with another one... temps at 100% load now are 77C sustained and this rad is definitely hot now

[Mindovermaster Global Moderator]

Yep, RMA it. Like I said, they can break easily. Even when new.

If you have the H100 extreme and not the H100 elite, the reason you have the heat issue is that it's the wrong cooler for a 1700 chip. Only the extremes are for the 1700 chip, I know as I had the same issue. The elite has a slightly bigger footprint.

I have the elite one that came with the 1700 bracket, it even says for 13th gen intel chips on the box

Got a replacement Corsair iCUE H100i RGB Elite and these are my temps after running for 30 minutes at full with prime95

Anyone telling you to RMA is an idiot who knows nothing at all.  Everyone's ambient is different, everyone's case air flow is different, this is why coolers are tested in an air cond sustained temp environment. 

AiOs also require some settling time, also you might want to note the orientation of the rad. 

The temp shown is of the cpu not the fluid inside, and whilst the radiator doesn't feel hot now, eventually it would. 

 

I would recommend setting the pump speed to extreme in icue. 

Prime 95 and others run a 5800X very hot too - which was why everyone was crying for the 5900x.. It's about the package. 

 

A 13900k has ALOT of cores in a small spot, eventually your radiator will get hot, mine does, but it's not an air cooler that instantly gets hot or cold, and it won't quickly get hot all over either it'll be at the start it begins to get warm. 

Like you I was worried, I have the H110i GT and it has been no different to my past two corsairs 280s, both got replaced by corsair under warranty. 

 

In terms of cooling, its highly recommended to keep pump on max speed, and again remember there's no instant hot or cold like air.

An example is a blocked radiator in your car - it doesn't instantly overheat - same with the blowers they don't instantly blow hot. 

 

In terms of weight I really wouldn't be that pedantic to weigh it. 

If your idles were 99 I would agree, but they are not.

Dude, you're the stupid one here. You even know what an RMA is? Clearly his AIO is broken, and needs a replacement.

except... the AIO was defective and replacing it with another of the same type, installed the same way and now it works just fine and is no longer thermal throttling... im not even sure the pump was running because the tubes wernt warm, and the rad wasnt warm, and the AIO temp sensor was reporting a temp that was lower than ambient temp.. the new one the rad is warm even idling, it wasn't warm at all with the broke one. and at full usage it blows pretty hot air now, the broke one was just cool air going through even after 40 minutes of burn in at 100% CPU usage (which thermal throttled like wild, and no longer does at all with the new one)

Hallo,

13900k uses a LGA1700 socket. Corsair H100i does not support it. You have to purchase an LGA1700 Retrofit Kit from Corsair web-store to make it compatible. If you used the wrong standoff your CPU and cooler do not touch. 99C is your thermal throttling protection in action. hope this helped.

No, I did not have to purchase a retrofit kit, the H100i Elite came with the parts for an LGA1700

 

Supported sockets in the box:

Current manual:

Standoff  Part C came in the box with the cooler in it's own bag marked as "For LGA 1700"

And the Elite's cooling block is 2 mm bigger. Not sounding much, but it makes a lot of difference. I know as I did have the same issue and the Elite made a lot of difference.

[neufuse Veteran]

I am using the Elite variant

[NinjaGinger]

Your first report did not report you are using the Elite. Which one. I use the H100 Elite as well, and I have no heat issues. I use https://www.amazon.co.uk/gp/product/B09HDJ3Z47/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

no, but I did say it later multiple times
