NH-D15 on 4790k@4.4ghz temps too high - Page 2

post #11 of 21
Thread Starter 
Good news. I set Manual vcore to 1.180 and now running Prime95 reaches 79ºC on the hottest core. That's 11ºC less than before!! And within the safe range for this CPU. My softwares and games won't make it run hotter than that. And now it's summer here, my room is warm, so the cpu won't get super hot during the rest of the year for sure.
I didn't find any LLC options in the BIOS though. Maybe I'll install AI Suite 3 to modify that, I remember it was there.
I'm satisfied with this configuration but I think I'll drop the vcore a little more and keep testing my temps and stability.

Thanks a lot guys. thumb.gif

PD: it's weird that a top manufacturer like ASUS provides BIOS that by default overvolt the CPU and provoke insanely high temps.

i would seriously recommend that you get a real case for the long run tho.... it doesn't matter how good of a HSF you have, if it's inside of an oven, it's still not going to cool down your chip smile.gif $29.95 case is not designed for a $1200 rig.... i would recommend you look into something like a fractal R5 or something in the $100 - $120 category. i'm surprised you are able to fit the D15 in the case... is it even possible to close the side panel with the D15 installed? it's one thing to have the side panel off for benching, but for long term everyday usage, you definitely want a case that can offer enough filtered cooling air coming into the case so dust doesn't destroy your system.

vcore is too high, and idle should never get to around 40. I've got D15S (one fan) and 4790K idles just 1-2 above room temps, usually around 22-23 degrees.

I set manually my vcore to 1.120 and now with Prime95 I get 72ºC on the hottest core (a couple less on the package). That's 18ºC less than with the Vcore in Auto!! And so far, it's running stable.
I didn't try to go even lower with the vcore, the improvement in temps is huge already and I could even set an higher frequency in the future. For now at 4.4 Ghz. Turbo I'm good. smile.gif

I see your point but I would have to buy a new desk too. No full tower badass case would fit here. And the desks I've seen everywhere are crap for little office cases.
I removed the side panel to install the NH-D15. But today I did some modding to it in order to put it back in. Believe it or not, I only get 1-2ºC more with the side panel closed. Nothing.

I don't know the weather where you live but it's summer here. My room is pretty warm. I don't have anything to measure my ambient temp with but I'm sure it's around 30ºC. Today there was 40ºC outside and a thermal sensation of 62ºC!! Humidity is high as well 70-75%. So I guess 35-40ºC in idle here and now it's not weird. I definitely won't get this temps the rest of the year.

well, as long as you are aware the case is not ideal for the rig that you built. i don't know the purpose of your rig and don't know what kind of GPU you are running that's why I offer that advice. if this is going to be a gaming rig, then the bigger problem will be your GPU rather then CPU since typically speaking a gaming grade GPU will put out far more heat then CPU will. w/o proper ventilation, the GPU will turn the case into an oven and that's when the HSF will suffer a major hit in performance.

with 30 degrees in your room air cooling is really gonna struggle. I suggest removing the side panel and turning up the fans on full on. I know how my rig struggles in the summer. installing any additional fans didn't actually make any difference since the intake air they're supplying is already very warm or hot even.
I would stronly advise against running p95 in such high ambient temps, because of the possible danger of overheating your components. It's better to stress test your CPU when the room temp is around 20, it has a huge impact on temps in e.g.p95.

What psyclum is saying is true.

In a 30c room you need the CPU(& GPU) coolers need intake as close as possible to room ambient. If you have not yet monitored the cooler intake air temp please do so. 3-5c above ambient is quite good. Problem is cooler intake air temps are often 10-20c warmer than room, even in cases with good airflow.

You're right, but I get almost 20°c less just changing the vcore. And even in the summer and in a warm room I think it's useful to do stress test carefully and stop it if the temps are too high. It's the most extreme condition to test your rig and configuration. And like I said the rest of the year the temps will be lower.

My rig is for normal use, internet surfing and download stuff mostly but also gaming and video rendering. The GPU is Zotac GTX 980Ti, it's the reference model with blower, the hot air it generates goes outside the case, it's noisier though. There's heat inside of course but it's less than with dual cooler or tri cooler model.
I don't have anything to measure ambient temps with. And intake air 20°c warmer than room??? Seriously??? My system should be literally on fire then. I don't understand what you mean.

just for reference, the TDP of the GTX980Ti is 250w while the TDP of the 4790k is only 88w. so at stock speeds, the GPU will output almost 3x more heat then the CPU. now take a look at the size of the heatsink on the GTX980Ti vs your NH-D15 and considering the amount of heat output by the GPU is almost 3 times that of the CPU... smile.gif i think you get where i'm coming from. granted the blower style cooler will exhaust most of the heat outside the case, but some heat will still leak into the case. having a good airflow inside the case will lessen the effect of the problem compounded by an already high ambient temp.

with that said, your temps are not unreasonable under load and considering your high ambient temp. the question is whether you can maintain that temp level when both CPU and GPU are stressed. you may not need a new case, but it's still something to consider for the long term health of your rig including consideration for dust accumulation in the long term.

My real life tests for CPU+GPU are games. The heaviest game I play now is AC Syndicate in Full HD maxed out (4.2gb VRAM) and I played for 2 hours at most without problems so far: 70°c tops on cpu, don't know the GPU it's set on auto, should be fine too). I never play for more than 2 hours so I guess everything is fine for now. And again: it's summer, the rest of of the year I'll get lower temps.
About the dust I'll open the case every once in a while to cleaned it up like I've doing for years.
So, everything is running fine for now. But I built this rig just 2 months ago, I'll keep in mind your suggestion and see what happens in the long term. smile.gif
