[SOLVED] PC Temps too high on Phanteks Evolv Shift? Help!

[hakar.ahmed]

I have upgraded to a GTX 1080 plus and 9600K CPU(not overclocked). I am using a Phanteks Evolv shift case and when the glass panel is on, the CPU temps reach 80-90 Degrees on load, playing Rdr2 ultra @ 1440p. The GPU goes up to 82 degrees and does not go past that. I am not sure if I should upgrade to a H60 watercooler, the current heatsink I have is a Cryorig C7, prior to this I used to have a i5 7500 & 1060 6GB but never reached these temps. When I take the front glass panel off, the CPU temps drop down to 50-65 on load, drastic change. I am also using some 140mm blue "uphere" LED fans, 3 of them, It also may be that they are very cheap and air intake suck on them. The Cryorig heatsink may be too small for this powerful CPU, would a H60 plus(bigger heatsink) and some better corsair fans make a difference? Thanks!

Yeah, it's a shoebox lol.

It affects the gpu's boost clocks.
Nvidia's Gpu Boost automatically 'overclocks' the core clock based on power and thermal headroom. The cooler it runs, the better.

I think that's your gpu? There's like 3 different SC(SuperClocked) models.
Anyway, the advertised boost clock displayed here is more of a worst case scenario. With the appropriate cooling, the gpu can easily boost over 100mhz higher.

I think I might change my Phanteks case. I got the h80i and the cooling for my CPU has drastically lowered, esp on load. 27-33 Idle and 40-50 on load playing rdr2. The video card however is always 82-83 degrees, even with those static new fans I got. the 1080 just runs hot, and in a small case like this, it doesn't have room to breath that well. I was playing Far Cry 5 and has a blue screen, the bottom said Memory_Management.

I'd undervolt the gpu, that'll bring temps down some. Also, try swapping fan directions for the upper fan. You could even use zip ties to the frame and add another fan interior to help blow air into the gpu side. You aren't limited to exactly what the manufacturer claims, those factory numbers are just the hardmounts.

I've never undervolted my GPUs but will figure out. The h80i has a push/pull configuration at the bottom while I have two 140s on the side, the bottom 140 is intake and the top is exhaust. Do you have a picture example on how to blow air to the GPU with zip ties?

Memory_Management, hmmm... that could be drivers or hardware.
1)Scan your PC for viruses/malware. Adwcleaner is a good free tool: https://www.malwarebytes.com/adwcleaner/
2)Run the Windows System File Checker: https://support.microsoft.com/en-us/help/4026529/windows-10-using-system-file-checker

If it continues, then proceed:
3)Run Display Driver Uninstaller to remove the current gpu driver and then install the latest recommended from Nvidia.

4)Run Memtest86 free version: https://www.memtest86.com/
Results should be error-free, and without system hangs or crashes.

I've never undervolted my GPUs but will figure out.

EZ mode is to use Msi Afterburner and either lower the power limit, or simply set a temperature limit, like 80C.

I used Evga Precision and lowed GPU temp to 70 Degrees and that also lowered the power of the card to 72 from both being 100 originally. I play rdr2, it seems to run the same as before, does this cause any issues by lowering Power? The temps are at 70-72 Degrees.

Yes, lowering power limits can do that. It's a dance, no different to overclocking an intel cpu except that instead of bumping the multiplier and lowering voltage as low as it can and remain stable, you are skipping the bump multiplier part and undervolting the card. You'll need to take baby steps, start with minimal drops on the voltage until temps are lowered sufficiently to allow full boost. If you can drop it to even 79°C by either adding a fan, changing fan curve, undervolting etc and get full boost then fps outputs will go up.

As for the fan itself, do a dry run, see where it'll fit and look like it will move air in the gpu's direction. On a standard ATX you'd just ziptie it to a hdd cage for instance. It doesn't have to move a ton of air, but it does have to move more than the gpu currently gets. Get creative! It may turn out that reversing the fan and having it suck the gpu exhaust and blow that towards the front exhaust fan is the key.

Temps on the cpu look awesome btw, there's too many people who discredit the H80i series because it's a 120mm, but it's a seriously good performer for mid wattage cpus.
