Problems with cooling a delidded 8700k

Jed78 · 10 Feb 2018 at 21:28

Hi guys I have today installed a delidded 8700k (bought from overclockers) and I am seeing some high temps. I have a ek kit p240 which is also new and installed today.

My temps are really high with 45c just idling. Put on Ghost recon wildlands to test the temps and they were jumping in their 90's. I was hoping to overclock this cpu til 4.9ghz as advertised but obviously with these temps I can't. I used Thermal Grizzly, a pea sized amount. I am at a loss as to what the problem could be.

Also can someone please tell me if I have the fans below as push or pull? Sounds daft But i wasn't quite sure and wanted it set up as pull.

Many thanks in advance

Have you tried remounting? Definitely sounds like heat isn't dissipating properly. Also you can tell if they're push or pull by putting your hand on them and seeing if you feel a breeze.

I might have to try that. Im not seeing a lot of action from the pump. Theres no big swirl at the top, i can feel it vibrating a little but looking at the tiny gap at the top I might have a problem with the pump? This has depressed me big time

You won't see swirl, once there are no bubbles in the loop it's difficult to see the flow. If it's vibrating when you touch tubes it's working. You can check at what speed in the system

Something is definitely not right. My non delidded idols in the high 20s and up to the 80s after an hour of realbench. This is air cooled and at 4.8ghz 1.25v.

I'm waiting on a bracket to arrive from Corsair to get it under my AIO - they put the wrong standoffs in my box.

I am going to ditch the water cooling, I am convinced there is a problem with the pump. I have ordered the Corsair H105 AIO which I hope will do the job properly. Fed up of filling and draining loops all the time, the paranoia I might get a drop of coolant on the mobo is killing me lol. If problem persists afterwards I am gonna assume it's a dodgy cpu, however I think its the Pump not pushing the coolant round properly. Looking in the water block I can't see any movement of the water inside either.

I guess give it a go and see what happens.

I got a 360 aio coming (good deal) and I'm excited in away to see how well it'll perform on my 8700k. Using a Noctua DH15 atm and the aio was such a good price I'd thought I'd finally use and have one myself. Your temps on a delid seem way off definitely.

I wish I had room for a 360 radiator. I'm hoping the 240 that comes with the H105 will be sufficient

My 8700K has not been delided and I was using a R1 Ultimate Dual air cooler.

I got 5.1 @ 80c. I have now left it at stock and it never goes above 60c. I just don't trust AIO coolers.

Assuming the radiator is behind the fans then they are pulling the air.

Wow my brother swore to me that they were pushing air through, I have since switched them over as I wanted pull. Will have to remember that when my AIO comes.

Is the pump plugged in? I made that mistake on my old H80i - forgot to plug the pump in post upgrade!

Edit: Looks like the fans are pulling air from outside the case - the logos usually face the exhaust.

Yes mate it is. I even tried powering it via another psu I had spare. It does seem to push the coolant round, but not very much by the looks of it. My old magicool DCP450 seemed stronger

MrRockliffe · 11 Feb 2018 at 17:14

I wouldn't worry too much about the speed of coolant - not all AIOs have fast pumps. Unless of course, it's slower than you remember it to be

It's not an AIO mate it's the EK-XRES 140 Revo D5 that come with the kit. It's either the pump or the CPU itself. I'm pretty sure I seated the cpu correctly, applied a pea sized amount of thermal Grizzly. If the problem persists after I install the H150 then it has to be be a dodgy chip.

Mate that pump going with a dual/triple rad(not sure what you have) is superior in every way to any AIO! there must be something wrong with the way you have mounted the block or are removing heat from the case. what block are you using, have you made sure the block is making correct contact and have you removed the plastic film from the bottom of the block, have you made sure the pump is going into the inlet hole and not the out let and lastly are you pulling air through your rad and out of your case so not to dump all the heat into your case(which was my problem)? My guess is there is something wrong with the mounting of the block because of the high idle. I don’t think there is a problem with the pump because if it wasn’t working you would hit shutdown temperature rarther quicky.

Put a piece of paper on the other side of your radiator and you will soon see if its push pull without having to ask others when your unsure.

Well that's one reason I bought the EK kit to start with. However after setting it all up, filling the loop, getting rid if air bubbles, then draining, changing the tubing and doing it all over again I'm fed up with messing about with it. I liked the xspc uv tubing and thought it might have been a problem with that originally so I changed it with the tubing EK provided and still same problem.

I was using the EK Supremacy evo which was provided. Pulled the stickers and plastic film of. I realise my cooling may not be as good but the hassle has annoyed me. Fitting a drain would have helped but my graphic card or case was in the way. So I have stripped all the EK stuff out and cleaned my CPU ready for the H150. As long as it cools it well enough for me to overclock to 4.9Ghz then I'll be happy

I bought a 360 aoi from overclockers uk for my 8700. After 2 hours running any game it hits 65c running at 5.1. The only time it has gone over 70 is when assassins creed had crap coding and used all the cores at 95% + .Got 3 fans pushing on the rad and it's had no problems at all.
