i5 4690k with Hyper 212 Evo horrible temps

[machg235]

Short and sweet. I recently upgraded to a i5 4690k from a FX6300. My temps are awful. I'm idling at 40-41 degrees celsius. While playing Overwatch i'm hitting 70 degrees. I took off the thermal compound that I put on a couple days ago (MX-4)(used to get 73 degrees while playing Overwatch). I totally cleaned it, and reapplied IC Diamond. I also rigged a 140mm fan to it since the stock one was the loudest part of my build. Nothing overclocked, and every fan slot filled in a Fractal Design Define R4. All fans running around 1000 RPM. Am i missing something here, or did I just epically lose the silicon lottery?

70c is perfectly normal and safe for that CPU. It's not even that Intel CPUs run warmer than AMD CPUs, but the temperature sensor is located closer to the hottest parts of the CPU.

Your chip will not throttle until 100c, and many Intel CPUs run at 80-90c for literally decades safely without crashing. Most on here will advise you to keep it under 80c, but you're still within the safe zone by that metric.

Thanks for the reply! It's not that I'm worried about it. I'm okay with those temps. It's just that I was hoping to over clock and that is a little too warm if I was going to push it farther. Other people are idling around 25 degrees celcius and hitting 50 under full load. That is a HUGE difference.

What is your ambient temperature?

and the internet is the internet. Either they won the CPU lottery or they are lying. Getting 50 with an overclocked 4690k seems unlikely. If you are worried about temps, I would take off the h212 check the spread of the thermal paste, and if it is not like a quarter coin I'd clean it and reapply a single +sized rice in the middle with artic silver5 or mx4.

What is your ambient temperature?

Around 65 degrees Fahrenheit. I live in Upper Michigan, we keep the house pretty cool, and it didn't get over 70 today. I thought his might be the problem, but my ambient temps are basically perfectly average (I would think). It's not like I live in Florida without AC or anything like that.

50c under load for a Haswell i5 seems unreasonably low, tbh.

You may be totally correct. I've only started dealing with Intel in the last 2 weeks. On the other hand, I've seen a few threads saying stuff like this

Tcase is the maximum allowable temperature at the top of the heatspreader. Unfortunately, there is no sensor there, so that temperature is unknown. Intel's mobile versions of these CPUs (which are the same physical die) have a maximum temperature of 100c. Additionally, under the stock cooler, some higher-end chips run in excess of 90c under some loads. Intel built these chips, designed this cooler, and provides a warranty for these CPUs when running under these coolers. On top of that, failure rates are virtually zero - I can't think of a single time I heard of a CPU dying prematurely due to heat.

Some may disagree with me, but that's where I come from when I give advice regarding temperatures on Intel CPUs.

In regards to the 212 evo, it should be cooling a bit better than that. Any 'turbo' or performance settings selected in the bios that may be auto overclocking the cpu? There's the four mounting screws to attach the cooler but there's also a threaded thumbscrew in the center of the cooler's base directly under the cooling tower. Try tightening that a bit, it adds some mounting pressure to ensure solid contact with the cpu.

Mine had that trouble initially. If I grasped the cooler I could give it a little twist on the cpu even when it was mounted without using much pressure at all. Tightening that center adjustment improve contact. It does get up around 70c but under stress testing with a light oc to 4.2ghz and with ambient temps a good 10F+ hotter.

Idle temps aren't overly important however with ambient temps that cool I would be looking for idle temps closer to 30c. This pc is also running a 4690k but with a larger cooler on it, ambient temps closer to 80F right now (gotta love the onset of summer) and with around 25-30% load my cpu's hovering around 35-36c.

A 140mm fan isn't likely to help your temps, 120mm fans typically produce higher static pressure because of their more focused airflow along a narrower path. As fan diameter goes up at the same cfm (air volume) static pressure usually drops. Pressure is what's needed to move air through the cooling fins. If the fan is loud it may be worthwhile checking to see that you're plugged into the cpu_fan header and double check the bios to see what your cooling profile is set to. Unless the fan is faulty or abnormal in some way it shouldn't be noisy. It shouldn't have to run full speed either most of the time.

To each their own on temps, I prefer to keep my cpu's around 70-75c max, under 70 if possible. If others want to cook their cpu that's on them. I'm sure others will disagree but I bet they won't offer to buy me a new chip if it 'were' to fail prematurely due to higher temps. It's a known fact that while electronics produce heat they don't benefit from excessive heat either.

Mobile cpu's may have listed higher temps but they also run with coolers even crappier than the stock intel desktop heatsink due to space constraints. A laptop also is designed to be a mobile (aka temporary) device, not a 24/7 workstation. Cordless hedge trimmers are great for pruning the bushes near the porch but I wouldn't recommend them for professional tree servicing either, it's cute for light work but it's not a gas powered chainsaw and nowhere near as durable. Everything has a role.

If the tiny coolers typical of laptops with a thin profile low speed fan that barely moves 20cfm were 'suitable' that's what intel would ship as a stock cooler for their desktop cpu's. Compare the size and cooling efficiency of a laptop cooler to a desktop cooler (stock) and consider that the desktop stock cooler is 'barely' enough. That alone says something. Intel does provide a warranty when using the stock cooler. Warranties are not an indicator of quality and that's widely known. Certain auto parts stores (you know the ones) have lifetime warranties on many of their parts and honors them diligently. When someone finally gets tired of replacing the same janky part 5, 6, 7 times they'll realize that the 'warranty' doesn't mean quality. They'll then go spend a buck or two extra and get something worthwhile, replace it once and be done with it.
