Good temps?

[agnes]

Running 2x EK 360 PE rads with Noctua NF A12x25. All fans run at around 1250 rpm in game. 800rpm idle. D5 pump running at 55% (2350rpm). No other case fans, bottom radiator pulls in cold air, top radiator exhausts the warm air. All in a Lian Li PC-O11 Dynamic XL.

Anyway, so the loop goes pump/res > rad > GPU > CPU > rad > pump/res. My CPU is OC'd to 4.8Ghz with 1.3v on the core (8700k delid), my GPU is a EVGA 2080 ti XC Ultra which is OC with +160 on the core and +1000 to memory, 130% power target.

My CPU package sits solid at 65C with max peaks at 70C and my GPU 55C after very long sessions but never much higher in a room with an ambient temp of 23C.

I think the CPU is a little high? GPU not so much, liquid temp is unknown but the above numbers are on a solid load to both the GPU and CPU, I've a liquid temp sensor, I've not not installed it yet.

Thanks all, I lost the silicone lottery big time with my 8700k, I've tried so many times to lower the v core but anything below 1.3 at 4.8ghz is just not stable. My wife's got the same cpu but doesn't oc... And I've delid hers... I wonder.........

 

[agnes]

LOL worth a shot do the old switch-a-roo, if she doesn't oc then no harm no foul XD

She's playing PoE right now, I was like 'hey, I'm gonna install the AIO for you today, and swap our our CPU's...'

'Hold up a minute, what?' lol. Needless to say, I don't think she minds as she literally runs it at stock.

What speed is the RAM running at?

XMP II profile, 3200mhz, but let me triple check.

 

[agnes]

Ok, something is up, running 4.8 at 1.3 vcore and within 30 seconds one or two threads fails in P95... Something is up. I'm thinking the CPU is on it's way out.

 

[agnes]

Yep, CPU needs 1.325 to stay solid at 4.8Ghz... I think it's time to upgrade to a 9900k... Last stress test which only ran for a few minutes got me to a max CPU package pf 77C with 75C being the average.

 

[agnes]

how long have you had it at 4.8ghz @1.3v?

2 years?

 

[agnes]

2 years @1.3v?, if so that had a good run.

maybe worth swapping it out for your wifes cpu, as if you run yours at stock speed it should still work, if not then the cpu may be on the way out

I agree, I mean it ran at 1.275 for a long time, towards the end of last year, I had to bump it to 1.3, now I'm at 1.325... So, I have a feeling it's run it's course.

Annoying as I just setup the new WC hardline loop so will have to drain to fit the new CPU. But, it's time. Off I go to buy a 9900k!

 

[agnes]

i'd still swap out cpu's first, use yours at stock in your wifes pc and see what hers does in yours, if your wifes pc develops issues at stock with your cpu then you can look at a new cpu, mobo combo.

if you do the swap and everythings good then you dont need to spend a pretty penny upgrading a 9900k and board will be the best part of £700 ish.

you may be able to run a 9th gen chip on your board via a bios update but looking online and it seems that there are vrm temp concerns due to the extra cores, if you plan to overclock, i'd advise active cooling or watercooling on the vrm's with a 9900k

what mobo do you have atm?

No need to get a new board for 9900k though.

My wifes 1080 ti is also acting up, I'd rather not risk making her PC even less stable if my CPU starts to throw a tantrum.

I'm about to head into San Francisco, Best Buy has one left in stock, just placed an order on it for pickup. Time for an upgrade! Plus, I need to drain my loop and install the liquid temp sensor and flow meter anyway, new liquid being delivered today. I can also make an attempt at bending some more tubes as some of them are less than ideal haha.

Also, I have a Z390-E motherboard, I thought I'd get it to future proof, it seems it was a good move.

 

[agnes]

dont forget to check if your mobo needs a bios update first, if you install the new cpu and dont update the pc wont boot!

Haha, just looking now, looks like I'm on the latest.

 

[agnes]

if thats the case your good to go, once installed check the vrm's and see if they are holding up ok (temp wise that is) if they seem hot add a fan for some active cooling XD

From what I read they were doing fine last I checked on passive cooling. Not the coolest, but nothing to be worried about. I was actually 2 versions out on BIOS. So I just updated, good shout! About to head out and get the 9900k, I'll update once it's in! I've been toying with it for a while, so even with this 'issue' likely being fine and liveable, I've needed any form of excuse to bite the bullet as I'm one of those idiots who just likes to have the best stuff haha. Plus, wife and I have been very good on spending over Christmas by not returning back to the UK for my family or Poland for her family and I'm not headed back for my birthday next week. Sooooo, nice little gift to my self

Bios update?
Did I misread it?
Thought you were swapping
A 8700k for another 8700k?
If I read it wrong
Sorry
And just ignore me

About to go pickup a 9900k

Time to go drain the loop

 

[agnes]

was that with the 8700k installed? i'd still check the vrm's after the 9900k's installed, it'd be a bu**er if you killed your board because that may damage your new cpu which would suck, get the new cpu installed and run a stress test and try to moniter the vrm's if everthings ok then happy days!

Just about to leave and I'm thinking I'll install another one of those noctua fans at the rear of the case put pulling air in to bring a fresh breeze over the vrms, can't hurt and will also get some fresh air in for the top rad rather than pulling all the dirty air from the bottom rad.

Just installed the flow meter and temp sensor, so I'll get back and just stick the new cpu in and get going. Thanks for your help mate.

You're all good mate! And no worries, I read your signature the other week, you don't have to apologise for that stuff man.

Thank you for your help in both this thread and the other!

 

[agnes]

your very welcome, i try my best to help all, been in the computer loop for quite some time and its nice to share my experence with others, let us all know how you get on with the 9900k, it should shread at gaming XD

Will do! And yea, last time I water-cooled was back when I had a E6600 and gtx 9800`s in sli. Long time ago. Been building pc's for years, but having to relearn a lot with the new standards of watercooling and what's to be expected.

It's 2pm here, I'll have updates in about 2 hours.

 

[agnes]

Welp, out of the box, it's running 15C cooler under Prime95 small FFT's, time to overclock!

 

[agnes]

Aaaalrighty! So, flow is good at 60%, I've sat and tweaked a bunch of my settings in Aquero over the past couple of hours. With the liquid temp sensor now in place, it's plateaued out at 38.5C after a long session in Red Dead Redemption 2. Thus I've adjusted my fans accordingly, ambient temp is 25.5C (got a ambient, case and liquid temp sensor attached to the Aquero).

The 9900k is at 5.0Ghz on all cores with 1.280 vcore, and whilst in RDR2, it's sat around 60C give or take, and GPU sitting a smidge under 50C. Overall, I'd call that a success!

And a teeny performance boost to boot.

With ambient at 25C, liquid temp is 28C which is amazing. GPU sits at 30C and CPU package sits at 32C. So both load and idle temps are very comfortable all whilst running practically silent under load and absolutely silent at idle.
