Do i need a better cooler to avoid crashes?

[Rick_89]

First off this is my first pc build so I'm fairly new to this. So after playing deux ex (which uses directx12, not sure if that matters.) My GPU reached 86 at max. I play most games at 4k and max settings if possible. I started streaming a movie through popcorn time after a few hours of play. After about 20 mins the screen went black and it sounded like the case fan went to full speed and didn't stop. So i restarted and when windows started to boot it would go black with just a white bar. I tried safe mode, same thing. I went into bios and picked load optimal settings and it worked. Since then I've had 2 crashes ( not while gaming) but it was a simple restart. I would think this is a heat issue but the only other explanation i can think of is the SSD is full.

My case has a 200mm fan in front, on the cpu there's a heat sink blowing towards the back, but i have no exhaust fan in the back. I want to get either an exhaust or top fan or both. I also want a new cooler since the 212 is huge and makes it a nightmare to get to the motherboard. I'm looking at this http://www.newegg.com/Product/Product.aspx?item=N82E16835181103
Corsair Hydro Series H100i V2
I don't overclock but might do some light OC someday, so I'm not sure if this is overkill.

So in closing, I'd like to find out if the crashes were related to heat, and what kind of cooler i should really have. My friend has a big bin of old used fans, not sure how old or dusty these are. Would it be a bad idea to try some of these out (120 or 140mm) for my exhaust fan? What brand should i look for? How many fans can i connect? Thanks in advance for the help.

First thing you need to do is to download a system monitoring software such as

CPUID Hwmonitor
http://www.cpuid.com/softwares/hwmonitor.html

or

HWInfo64
https://www.hwinfo.com/download.php

This will tell you what temperatures your system is seeing. You should also download a stress testing software like

Prime95
http://www.mersenne.org/download/

Now realistically your usage should not generate high heats so if they are up there then something is wrong with the build. Run the software under normal load and under stress test and report the results here.

It could be a number of issues that are causing your PC to crash.

First off, in a relatively small form factor case you expect the GTX 1080 to run hot; as it's a high end GPU, but 86 degrees in gaming shouldn't be a problem however I would install two 120mm or 140mm in-take fans to the top of the case and one as an exhaust on the rear, just to improve the cooling situation for the CPU and GPU.

Secondly, the GTX 1080 while watching film is basically running just above idle, so I do not see the GPU being the culprit here. However, I would check to ensure your CPU heatsink in making good contact with your i5, as overheating of the CPU will cause the computer to crash; as a safety feature to avoid damaging the chips. Perhaps even removing the heatsink and re-installing with fresh thermal paste; long task in a small form factor case but it will remove a tick from trying to diagnose the issue.

Thirdly, looking at your specifications; it's pretty powerful. I would suggest checking your specifications with a power supply calculator (http://www.coolermaster.com/power-supply-calculator/) as I am worried that maybe your components are not getting enough power from the 650watt PSU; it's worth a check.

Good luck, hope it's an easy fix.

While on the high side 86C under load is not out of the ordinary , especially in a small case.

I would advise before opening anything up to download the software and see what the system is doing. Based on the data from that you can start to focus on a solution. I would be more suspicious of a failing component like a memory module than a heat problem. This would be more in line with the intermittent failure mode that is being reported. A CPU heat issue will cause the CPU to start thermal throttling before it caused a system crash. But let's get some data first, otherwise we are just people with opinions.

Also, I highly doubt that the PSU is an issue, a 650W on a stock system is probably only in the 50% utilization zone, if anything it is maybe a little overpowered. The Outervision calculator on the Cooler Master website only comes in at 326W for the components listed which includes your big power consumers, the CPU and GPU.

If you use the Corsair h100i V2, you will not need any other fans added. Mount the cooler to the top in an exhaust position (pull is better). That's all you'll need. An exhaust fan mounted 90° to the upward moving air is pointless. Any heat put out by the gpu will also go through the cooler fans, heat rises naturally, but makes little difference to the cpu.

For Intel temps, use Realtemp, not hwinfo or Hwmonitor, it's more reliable, easier to read, and is designed to work with Prime95. If you use Prime95 for stress testing for temps, hunt down version 26.6, do not use any version later on that cpu or you'll see some ungodly high temps that are totally unreliable as versions after 26.6 use extremely high AVX usage, which no programs other than p95 use to such a degree.

It is possible that the issue is with the psu, regardless of the load. The Evga NEX, G1 supernova psus are not very good, and can be somewhat unreliable. Make sure the psu intake stays clean.

Ya learn something new everyday.
