i7-4770k Overheating badly. Help.

Nolazco · Aug 19, 2015

Over the past couple of days my pc has been overheating pretty badly. It idles at about 40C but when I'm running even such a game as Runescape it goes up to 92C even my Temp3 on speedfan goes up to those temps. My GPU is running at around 51C. Please note that I did ship my computer from USA to NZ than back again to USA. (That might be the problem) Would appreciate any help.

My Specs are as followed:

CPU: Intel® Core™ i7-4770K Processor
GPU: NVIDIA GeForce GTX 780 - 3GB - EVGA Superclocked
Cooler: Corsair Hydro Series H55 Liquid CPU Cooling System
Mobo: Gigabyte GA-Z87-HD3
Power Supply: 750 Watt - Corsair CX750M

First off, that isn't a very good AIO cooler for your CPU. The 4770K and the 4790K get very hot especially if you overclock them. You need a AIO cooler like the H80i/H100i/H110 depending on what your case can handle. Your PSU is also of lower quality and you would be better off if you bought an AX, HX, or RM series Corsair or a higher end Antec, or EVGA PSU. There is another brand, but I can't remember them at the moment.
I've had friends that had a lot of heating issues just because the PSU couldn't handle the job anymore. Your wattage for the PSU was fine. You just need to go with a better rated one like 80+ gold/platinum/titanium certifications.

Before I didn't have any problems what so ever . (Had the PC for a little over a year now) I also don't do any overclocking, I just do minimum gaming.

Its more than likely the crappy PSU. Moving between two different countries is horrible for PSUs and that PSU wasn't good enough quality for those components to begin with. So combine all of that together and you get overheating. If you have have high amperage and low voltage which starts to happen as the PSU ages or is just not made well then that will cause your heating issues. Same concept applies to cars and car audio systems when the draw on the power is too much.

Moving a PC about can cause parts to become loose or misaligned. I would start by taking the cooler off the CPU, giving it and the cpu a proper clean and reapplying thermal paste and reseating it.

Also are you sure the pump is still working?

If you just moved the computer you might want to try re-applying the thermal paste and re-installing the AIO; I'd recommend a cooler better than the H80i if you decide to replace that H55; like the H100i GTX or the Kraken X61 or a good air cooler like the Noctua NH-D14; I have an H80i on my 4770K rig and it does a pretty terrible job as far as cooling. The X61 on my 5930K keeps it at 71C max while gaming with all 6 cores @4.5Ghz.

How could I check to know if its that CPU's problem or the Cooler.

sizzling · Aug 19, 2015

Put your figure on the top of the cpu cooler, you should feel a tiny vibration if its working. If its not working check its still plugged in securely. My guess is you need to reseat it with new thermal paste.

If you reapply and reseat the cooler on the CPU and you have made sure the pump is still working then that will be the CPU having the problem. More than likely it will be the PSU in this case.

@loki: The only reason why your setup is that cool is with that CPU is because gaming only uses 4 cores max regardless of how many you actually have. So, you are running essentially a 4 core CPU when gaming. If you keep those same temps while rendering in Autocad or some other editing or rendering program then I would tip my hat to you. But, I highly doubt you will keep those same temps.

Actually, no. During stress testing with both computers the 4770K @stock 3.9Ghz on 4 cores with H80i hits 80C while my 5930K hits the same @4.5Ghz on six cores. My only computer that runs hotter is my i7 960 @4.1Ghz with an H50 which hits 88C under stress testing.

sizzling · Aug 19, 2015

Can I just point out a PSU cannot directly impact a CPU's temperature. An overstressed PSU might dump extra heat into the case but even that would have a marginal indirect impact on CPU temperature.

jdcranke07 · Aug 19, 2015

@Loki: Okay, so you are comparing two completely different things now. If you're gaming then you only use 4 cores period. If you are stress testing then you use all cores. THEY ARE NOT THE SAME THING. So, in turn, your comparisons are like apples to oranges. It doesn't work that way.

@Sizzling: Then please read up on electrical currents. If you have to much pull on a system and the PSU cannot supply that much, then you will have added heat in the wiring and this will eventually cause it to catch on fire if the voltage falls enough and if the amperage is getting higher. It happens in car audio systems all the time when you have DIY'ers catch their cars on fire due to bad setups. It's the same concept in computers. If the PSU has been moved and used on two completely different voltages, regardless of using converters, then the PSU can still be stressed enough to fail faster than if you hadn't moved the PC at all. That series of Corsair PSU is crap and has a very high fail rate compared to it's better brethren under the same company anyways and moving it around via USPS or whatever definitely did not help in any way.

Point is, whether gaming or stress testing 4770K with H80i runs hotter relative to 5930@4.5Ghz with X61 and only marginally cooler @3.9Ghz than my i7 960@4.1 Ghz with an H50. Like I said, H80i has not impressed me.

jdcranke07 · Aug 19, 2015

loki1944 :

It hasn't impressed you because you're not doing a proper comparison. You are using two different CPUs with two different Coolers and have not said or provided any data saying you have used both coolers on both CPUs. Hence, why your comments on the H80i are invalid and are giving false testimony over its performance and quality as a cooler. When you learn to do things properly, please share your results and we can further discuss the H80i coolers performance.

Also, I have an H80i on an AMD 8350 OC'd to 4.6Ghz with a slight BUS OC as well. It hovers at approx. 30-40'C at idle speeds as AMD systems do not detect temps correctly at lower temps. When gaming it never goes above 60-65'C and when stress testing it, it tops out at like 75-80'C depending on room temp. This is all while it is in a cabinet as well. That CPU is easily hitting the 125W mark if not higher and I have no problems with this cooler at all except for I would rather a dual 120mm rad, but the case won't allow for that. And as far as that CPU goes, it doesn't get that hot during gaming because I am only using 4 out of the 8 total cores it has. When stressing it, I am using all 8 cores.

H80i performance with 4770K @Stock=80C under stress testing, a mere 8C less than an i7 960@4.1 Ghz (900Mhz overclock) with an H50. That's all the proof I need.

You do realize as well that the CPUs would have to be in the same exact case and have the same component setup as your 4770K build does in order to compare that. Different cases, components, cable management, and fans will all make a difference in between the two tests. And you're doing something wrong with your setup if an H50 cools better than your H80i. Hopefully, you don't have a failed pump and you just haven't realized it yet.

Okay, so my first question is this, I think I'm going to get this PSU

Was also wondering since I'm just switching the PSU do I have to rewire everything again with the new wires or can i just disconnect the old wires then remove and replace the PSU and plug in the old wires again?

You never want to use one components wires for another unless you're talking cables like SATA or something like that. Shoot we as a community shun reusing hard drives from older builds if you don't have to.

Jdcranke07 you are taking theories about electronics which dont apply to all scenarios and especially this one. The voltages and currents the CPU use are controlled by the VRM's therefore the PSU cannot make a CPU heat up from extra watts. For your theory to apply it would need to be a failing part in the CPU for it to cause increased heat in the CPU.

Now a failing PSU may overheat but that would only dump hot air in the case. If the voltages went outside of acceptable ranges the PC would be unstable or unable to boot.

Apart from a possible raised case temperature a PSU cannot cause a CPU to run hotter

Says the one who confuses voltage and amperage with watts. Not the same thing. And if his motherboard is overheating due to a bad PSU powering it then in turn everything else plugged into the motherboard will suffer as well. Mostly the CPU. Because when a drop in voltage happens from the PSU, the mobo has no way to compensate and so it drops the voltage on the CPU and other components as well. This is all within overclocking 101 too btw. This is also coupled with possibly higher case temps due to the PSU getting hotter, as you did mention, due to being stressed beyond what it should be or if it has a hardware issue from being moved around. So, in turn my answer still stands.

Got a new cooler and that completely fixed the problem. Got told many times by friends and people that PSU doesn't affect overheating.

If you understood you would realise why I inserted watts when I did, remember the basics watts = volts x Amps. A PSU cannot cause a CPU to run at a higher voltage or current so therefore wattage.
