Looking for a good HSF for a 4790K on a microATX motherboard

Hey all. My 4790k is... sad. If I really push it with games or any sort of rendering, its temps skyrocket to 100°C. I'm running it on a Asus Z97M Plus motherboard. I've been looking at a Noctua NH-L12, but I worry about the fit.

I'm not going to overclock (I have a curse), but I'd like the CPU to at least live a little while.

Any thoughts?
 
what case do you have?
we would need to know that for height clearance...
 
Any normal tower case can fit an Arctic i11 $23. From Amazon user reviews:

Having problems with high operating temperatures on my i7-4790K CPU and the stock cooler that comes with it. This cooler reduced my idle temperatures by 1 ~ 3 Celsius, and most importantly, reduced my peak CPU temperatures during heavy operations (e.g. compiling and gaming) from 95 Celsius to around 70 Celsius.

Keeps my 4790k not oc'd at 75 max while under full load for 2 hrs.

I recently upgraded an older HP AMD system with a new motherboard and i7-4790K 4Ghz processor but realized with such a high powered processor and a mini tower case finding a heatsink was going to be a challenge. [...] It exceeds every expectation for cooling with core temps at 60 degrees at 100% load with turbo boost enabled

I installed this on my intel i7 4790k and temps dropped 10C going to this from my Cooler Master Hyper TX3. Idle temps were 25C and load temps hit around 72C. [...] I agree with most of the other reviewers in saying this cooler is defiantly quiet, I can't hear it over my case fans.

From product FAQ: "The height of the cooler must not exceed 140mm from the motherboard. "

Arctic i11 is 130mm tall, it'll fit easily
 
It took me a while to see your HSF. You shot that from directly on top. I was looking for the fan. What do you use your Quadro for? CAD?
 
I'd suggest turning the CPU fan to blow back towards the rear fan slot. I.e. the opposite way it is blowing now. Right now it's taking in the warm air that the graphics card is exhausting (and to a lesser extent the Quadro as well as the PSU). Then the CPU fan is blowing warm air from the heat sink into the case, warming up the case's air temperature, which increases graphics card temperatures and PSU intake temperature. Of course, your CPU temp is fine now, but the airflow is incorrectly set up and temps would be even better (and/or noise lower) if you switched the fan around.

It'd also help to have an exhaust fan installed in the rear fan slot, judging by the photo it can fit an 80mm fan. Like this one. You can measure the spacing to be sure, it should be 71.5mm between adjacent screw holes. It looks like you have a free fan header right next to where the CPU fan is plugged in.

I knew it looked funny. I had to go to the website to see how the caseflow was supposed to look? OP, do you have any intake fans? At the least you need to follow the advice of lehtv. That's what I would have done first before I purchased a new HSF.

I've got a four monitor setup, one 3440x1440 on the 980Ti and another 3440x1440 plus two 2560x1600s on the Quadro.

Yeah, I went in with that intention, but installed the HSF backwards. I didn't realize the fan could only go on the one side until I screwed it in. 😳

I'm going to be doing some serious rearranging in the near future (I'm moving and doing some monitor shuffling plus adding a sound card), so I'll fix it then.

Honestly I'm not so worried about the temps as long as they stay below throttling level. This rig is just standing in until Kaby Lake hits, assuming anything ever seriously surpasses the 4790. 😛

That's not going to be a worthwhile upgrade in terms of CPU performance. 🙂 4790K is on par with 6700K, just consumes more power... and Kaby Lake is not going to be anything more than a marginal improvement over Skylake.
 
I have used cooler master hyper 212 evo for over a year, even ran it at 4.4 ghz, temp hovered around 65-68 at full load
