4790K too hot - need advice.

post #1 of 10
Thread Starter 
Hi I just got my 4790K yesterday, but it runs hot as hell, literally. 35-45 in idle and reaches 82 in games. This is certainly related to the fact that I did a horrible job on the thermal paste. I only had leftovers of almost two years old thermalright chill factor and mx-2 and I mixed them toghether to make it enough (I knew it was stupid). To make it worse my TR Macho 120 has some ugly green stains on 2 of the heatpipes which look like rust+mold and I suppose they are responsible too. I just ordered a brand new D15S but it's gonna be here Monaday, I still have the stock cooler (unused). Will it improve my temps until my Noctua arrives ?

If you don't have enough thermal paste to reapply for the stock cooler, then switching out is a bad idea. If you do have enough thermal paste, I would swap out for the stock cooler. That being said, 82 degrees is not a crisis; if you can't swap it out for a couple of days, I would keep an eye on it, but wouldn't be really concerned about it.

is that so ? smile.gif
one more thing. hwmonitor reports core 1 hitting 94-98 degrees (max temp recorded), but the thing is I never actually see this temperature in afterburner, I also have a BIOS warning enabled over 90 but it hasn't shown yet.
Are those real 1 seconds spikes of 90+ degrees or just hwmonitor reporting it wrong ?

Sadly, this may be the new norm. Delidding may be your only choice really. Expect about 10-20C improvement after a delid. The reason why is because there's a black adhesive paste between the die and the core that increases the distance.

A new CPU cooler will only have a limited effect. It's the fact that the CPU uses solder and not paste [on HEDT , versus on mainstream that use paste] that is responsible for the problem. That being said, switch it anyways, as the stock cooler isn't good. Even assuming an ambient temperature of 22C, and no overclock, the stock cooler will throttle under IBT.

82C is pretty normal for CPUs that don't use solder and use paste. You'll have until I believe 105C until shutdown, and throttle a few degrees below that. The HW Monitor is likely correct.

Only the HEDT CPUs come with solder these days. The other option is to switch that 4790K and the motherboard for a 5820K and an X99.

My 4790k is idling at 27c 26c right now. 60c is what I'd consider hot in a game. This is at stock settings with a H100i. Ambient temperatures are 70f/21.1c. Sounds like even your ambient is high, or, you need a better cooler. As for stress testing, I've only used approved stress tests such as "Asus RealBench", and "AIDA64 ". Prime95 and intel burn will run these CPU too hot and was not recommended last I checked.

I reseated the cooler and replaced the paste with some mx-2 I borrowed (it was almost 2 years old too, does this have any impact ?). Temps went down by a few degrees but that's all, although now I'm measuring with higher temp in my room than yesterday since it's 5 PM and the day is hot. The results I gave you were from yesterday night.
I'll replace the cooling since 3 out of 10 heatpipes on my TR120 are rusty. One is real bad, two other have 2-3mm stains. Must've been from the time I spilled the coffee on my PC, might've been a few drops getting inside and landing on the pipes.

comparing a 240mm CLC to a 120mm air cooler, I'd say 20 degrees difference in gaming temps is about right given the fact it's around 25 degrees in my room (possibly more). Idling at 31-35 (coolest to warmest core). Our delta temp in idle seems not so different.
Can't wait for my Noctua D15S, love the looks of that cooling thumb.gif

edit: I told you my idle went down a bit, now get ready to hear this. In FC4 I'm running below 65 all the time, I was hitting 84 in the same game yesterday. That's actually the same as my 3570k 4.5GHz 1.264v Boy, did I screw this up yesterday applaud.gif HWmonitor shows max temp of 80 degrees on core 1 but it must've been a short spike cause I saw nothing higher than 65 in afterburner OSD.I suppose those milisecond temp spikes are a thing on Devil's Canyon, only yesterday they ranged from 92 to 98 degrees devil.gif
Expecting to run below 60 with D15S biggrin.gif

Yea, sounds about right. I run the H100i on quiet settings and it handles cooling this 4790k well like that. I know the H100i is more for show then performance so I'd imagine that the D15S should be able to keep it within my temp range easy enough at stock.

Well, there's another thing.Not only did remountingthe heatsink help, I think I've been using a wrong software to read my temps. What do you think ? HWmonitor shows temps which in most cases are from 5 to 10 degrees higher than in realtemp,aida and ab. which one to trust ? There are 3 programs giving me good temps and one giving much higher ones.

In The Witcher 3 Realtemp showed 43-59 across the cores (core #1 hottest), AB showed 47-55 (also c#1 hottest) and HWmonitor showed 48-68 on core 1. Seems pretty consistent, around 10 degrees more on hwmonitor, the temp amplitude grows with core load (core 1 is always the most loaded in my PC, light or heavy load it's always got the highest % load).
And I'm sure I'm not the only person who spotted this difference, I remember other people complaining about the difference between hwmon and other soft.

You know, I've used HWmonitor for a long time because it was so lite. Since the move to Windows 10 I've noticed that it's very wonky. My min and max clocks for instance are way off. Min will often say 50MHz, and max 4600MHz even though that is not possible. I'm running my 4790k at stock and other programs pick it up as the correct values (800MHz low, 4400MHz high). I even went into bios and made sure my mobo wasn't doing a auto OC. It wasn't. Some of the voltage readings also seem to be reading the wrong part.

I haven't noticed anything odd with temperatures, but, I wouldn't be surprised if they were off now also.

So yea, HWmonitor might not be the best program to use right now along with windows 10 for monitoring your vitals.

I've been using it for years too since it's very clear to read and reads just about everything but if 3 programs show 20 degrees and hwmon shows 30 consistently there must be sth off about it. Plus it gives me weird readings on my PSU lines, sort of readings which would never even boot my pc let alone run stable if they were real.

this is a barely 10 months old Super Flower Leadex Gold 850W, rock stable since day 1. Whaddya think @shilka smile.gif? Is this sth to be alarmed about ?

edit: this is my 4790k stock on d15s, freshly installed, 11 minutes in FC4 1440p. I know this is barely any stress but on my TR Macho 120 I'd hit 65 already, even after the re-installation and re-pasting. I'm telling you, there was Mozart's 40. symphony in my head when I saw this biggrin.gif

I was like "get outta here...." biggrin.gif If you read my previous posts this is just incredible.... Frankly IDK why people are complaining about this CPU temp, you can't put a $30 Evo on it and expect to run cool, this isn't SB anymore tongue.gif I'm gonna get a second (possibly third) 15cm fan too, since my 54mm RAM looks like low profile sticks there's so much RAM clearance thumb.gif
