Hello, I have recently installed Seidon 240v to my i7 7700k build but in games such as Attila Total War, Fallout 4, Witcher 3 and such it reaches 70 to almost 80c. I'm even too scared to do a stress test as I think the cpu can blow up then :D It's not overclocked at all, running at stock speeds. My mobo is Z270 Gaming M6 if that matters. Have I installed it incorrectly? or can my cooler be faulty? thanks in advance!

(Also the two fans are intake sticked to on top of the case, blowing directly onto the cpu. And the double fans are connected to cpu fan, while the pump is connected to I think something that said pump on the mobo, I connected it there as it was no brainer but who knows. Right now it is 45c and I'm not even doing anything but typing this. I would say air flowing is nice and all, even if it was bad I don't think it legitimizes the heat of the cpu, and room celsius is about 24)

Hi, the temps at idle should not be that high period. As Marko55 says, I would reset the AIO and make sure it is installed properley. A pea sized ammount of TIM on the CPU. Make sure that the AIO is seated propely and then tighten down. I would also have the AIO exhausting out of the top with Fans at the front drawing air in. 45 degrees at idle is not good as who knows what full throtle on all cores will deliver in terms of temps. Also check to see the speed of the pump via any monitoring tool. My Gigabyte motherboards APP shows me the speed of my pump..just to make sure your pump is running at the correct speed or if on at all.

Should be the other way around. Roof-mounted rads should be exhaust, not intake. And yes, do check to make sure your cooler is mounted correctly with adequate paste and proper mounting pressure and the whole nine yards.

Check your Vcore. You could have an abnormally high auto voltage. I've heard plenty of horror stories of motherboards attempting to push 1.4V+ (I've seen 1.6, it's scary) on auto voltage. If that's the case, you're going to have to either use the - offset to subtract enough to have a more normal Vcore, or just manually enter a value.

Either way, the 7700k is a really hot chip, and the whole Seidon series wasn't very good when it was new. If all else fails, just RMA the CPU. To me, load temps of 70-80C with a second-rate AIO and an ambient temp of 24C sounds like it's on the high side of normal. I wouldn't bother with the whole delidding thing just yet; no point voiding your warranty when you're still covered by it.

I told someone else this recently, but when we buy Intel CPU's, we aren't only playing the silicon lottery, but the production standards/QC lottery as well.

Well, Vcore is 1.192 and overall pretty much 1.20. Isn't that normal? And the cooler can't be that bad! I've barely reached 70C on fx 8370 with hyper212 evo air cooler. Anyway to tell if I put on the thermal paste incorrectly? I used the usual smaller than pea size on middle of the cpu. And any details on why they should be exhaust? I would just like to know, the front two ones are also intake, and there's one exhaust on the back. And I don't have the courage to try that delidding thing, atleast not yet. And in the games I mentioned I haven't seen cpu usage going above 50% using afterburner. :p Thanks again!

I was gonna say "no", you don't need those radiator fans as exhaust because the fact is you absolutely don't. It's your option to pull cool air in from the outside to cool you're radiator. It's just that many people, probably most in fact, put them as exhausted. I've built multiple custom liquid cooled machines with them as intake. However, if you've got two intake fans in the front of your case then absolutely get the radiator fans flipped to outbound. You've got too many fans blowing air in to your case. This change may help things.

It's possible the thermal paste isn't applied as well as it could be. Spread it on to the cpu with a credit card very thin, then seat your cooler. Make sure the cooler is seated well of course. Most AIO systems just stop letting you screw them down so you know when you've reached the right point.

Yes, 7700K's run a little warm but this is not normal at stock speed. We should not even be talking about or considering delidding here. That makes no sense. That cooler is not the best ever but is perfectly adequate to cool a stock 7700K. I'd also check the bios setting for the fan connector you connected the pump to. Make sure it's set to a performance mode so it's RPMs are up pretty good. That can make a difference with AIO coolers big time.

thefrostorm,

This happened to me!

Download cpu-z to know the core speed.
If it is larger than 4200Mhz, go to the BIOS and disable the option "Intel Turbo Boost"
