9900k - High Temps all of a sudden !

Morning All,

I'm really scratching my head here on an issue I got with my 9900k on a Maximus X Hero and H110i.

I haven't really been doing anything on my PC for a good few months now, I mostly remote into it from the office and run some VM's in Workstation which never puts it under stress.

Anyway, on Friday night I installed the new Cinebench after spotting the thread here with everybody's benchmarks, my first run BSOD'd WHEA Errors and I noticed temps hit over 100c almost instantly. I pulled the PC from under my desk an noticed quite a bit of dust in the rad so I got the Dyson on it and gave it a good clean, I also took of the waterblock and reapplied a fresh coat of thermal paste (Noctua NT-H1 - Not sure how old this tube is).

After putting back on the block and putting the PC back under my desk I dialled in a manual overclock 1.275v vcore with LLC 6 and set all cores to 5ghz and booted to windows, all is good and I ran a few cinebenchs, temps never exceeded low 90s.

A day later I am gaming Project Cars 2, ACE Combat and I can hear my fans ramping up to max, CPU is in the 70s which is not normal when gaming. I tried a cinebench run and BSOD again with temps hitting the 100s almost straight away.

So I set the bios to stock again and tried cinebench again, temps are now hitting hight 90s at stock instantly.

The way the temp hits high 90s is making me think that there is an issue with either the Thermal paste or my H110i pump.

iCue is showing pump doing its job spinng above 3000rpm and a water temp of in the 30s.

Any Ideas what the issue coud be ?

Things tried so far :

1) Clean Rad and reapply thermal paste - Fixed the issue for a few hours
2) Bios Flashback & stock settings - Still High temps
3) Ordered some Konductanaut on Amazon Prime will arrive tonight - will report back

Notes :

Vid seems very high -

Well to me it sounds a bit like you’ve got an defect AIO unit. Or maybe it has something to do with OC’ing and voltages, which someone else in here as to comment about, since that is out of my knowledge area.

I'd keep an eye on that...

If it happens again...see if one of the tubes leading from the block is warmer than the other...sure sign there's a flow problem of some kind

Joking aside, I would do this. Confirmed the pump in my old H100i had died despite it showing normal RPM on Corsair Link

OP

Cinebench is the most demanding CPU bench I have seen so far and will knock over a lot of PCs with otherwise stable overclocks.

Test your setup with your normal software and see how things work out.

Getting over 100c again in R20 and R15, case is in bits at the moment, when I move the rad a bit temps drop, did a RMA with Amazon, new one should be here tomorrow !! Corsair products are a pile of dog shi* nowadays... Stay Away from them !

New H115i recevied this afternoon and installed.
Temps are much better, in fact the new pump is spinning at 2800rpm on extreme profile instead of over 3000rpm which obviously means that the old H115i pump was most probably spinning in a pocket of air.

Anyway I hope there has been no long term damage to my CPU, really not happy with Corsair products at the moment This is my 3rd H115i in just over 1 year. Im also on my 3rd Corsair Link. Thank God Amazon have no issue delivering next day for replacement.

Here is what the temps are now at with a Cinebench R20 run ->

Don’t get what people are moaning about/regarding Corsair really? If you have a bad experience with a product, sure it sucks, but that doesn’t mean that the company is automatically bad cause of it. And if it’s broken or defect, just contact them for a replacement part or just go buy another of the same product type. Why moan all over a forum about it? That no one will actually give a sh*t about, I mean for real here. And it will just make you look like an immature adult.

If your car breaks down, do you then ditch the manufacturer just because it broke?...

I’ve never had any issues with any of my Corsair products, and I’ve had several memory, AIOs and PSUs from them. But if I do have any issues, sure I ask for help here, but I don’t go flame the manufacturer behind it cause it’s a bad unit. This is technology people and technology unfortunately doesn’t always work to 100%.

In fact, nothing in life does, we just have to learn to live with it and move on, even if it does suck. That’s called life - grow up and deal with it!
