Evolved: lower fan speeds at higher temperatures? ...Too... Assist in saving or diagnosing my PC.
Current fan/case configuration:
- Fractal design r5
- Two front 120mm intake fans (below CDRAM) bottom is noctua 100% at 60°C, top is case provided and managed by a 3-notch speed controller on the front, unsure of its speed
- One bottom 120 noctua intake fan just next to the PSU 100% at 65°C
- One 120 noctua rear exhaust fan directly behind the CPU cooler 100% at 55°C
- Dark Rock Pro 3 cooler 100% at 50°C
I have OC's CPU, ring, RAM, and GPU. The GPU is a powerhouse reaching 1560Hz and 74°C.
CPU clock runs at 4.5 GHz with maximum temperatures up to 80°C, which feels quite high for this build, and a modest OC, any advice?
I use time spy and core temp monitoring.
RAM OC's specifications are listed. 1.275 core voltage. 4400 ring frequency

You need to match the number of fans on both sides for intake and exhaust to carry heat effectively. In your situation, having equal fans in exhaust and intake is recommended. Additionally, consider adjusting your processor's overclocked settings, as increased voltage can boost clock speed but may reduce lifespan when combined with high voltages.
TL;DR: The registry cleaners caused the ring ratio and voltage OC to become extremely unstable. Thanks! Sorry for the delayed reply. I think the fan placements are fine, but the cooler is in the top left near the exhaust, with the exhaust fan helping. The bottom intake and front right intake direct cool air toward the GPU. The other front intake sits just above the others, aimed at the cooler and RAM. It seems a bit of a debate, but guides suggest more intakes than exhausts. I’ve lowered the intake speed, spent time on OC guides, and adjusted settings.
Results: Amazing! 6367 in time, 13th best for my build – GPU is performing great! Still, temperatures are too high.
After cleaning the registry, things got worse. I reinstalled the cooler twice (yesterday was the last). I’m pretty sure I can’t install it directly into the case anymore. The best option was removing the motherboard, but a friend helped reattach it after minor scratches on the GPU. It’s still not perfect, but it’s better than nothing.
Then I ran a registry cleaner again… and it messed everything up. I got a BSOD soon after, which got less frequent over time. I tried reinstalling the registry with the provided file, clearing CMOS, and reinstalling NVIDIA drivers multiple times. Eventually, I ended up running the registry cleaner six times before finally restoring everything.
Why would anyone do this? Honestly, I’m an idiot. The original install didn’t seem to work right after I cleaned it, so I ran it again after troubleshooting. Now I can’t exceed 4.3 ring ratio – that requires 1.24v!
I’m currently doing a full system reset to fix these issues and will check the BIOS afterward.
Any advice or explanation would be greatly appreciated. Thanks!
Using a 4790k with a vcore above 1.3v shouldn't be an issue. It's surprising how often temperatures spike despite these settings. There are many other factors to consider beyond just the ring and vcore, and if you haven't adjusted most of them, stability is unlikely. What's your LLC setting? Any recent changes? Disabling eco controls or C-states might help. I recommend fixing the issue first, then checking temperatures. Also, pushing the vcore to 2.4v could damage the CPU, so I'd run stability tests using Asus RealBench.
Lol wow.. no.. my bad! This post would be quite different: "how to clean melted pc off desk?". My ring voltage was at 1.24v! And I agree it's a lot too high for comfort! Although the maximum threshold is really closer to 1.25v, as long as temperatures are under control... As I mentioned before, I managed a 44 ring ratio at 1.19v.
These were my last recorded settings just before resetting my PC, and I reset them back to the stock values before the reset.
CPU ratio mode: Fixed
CPU ratio: 46
Ring ratio: 43
CPU base clock apply mode: next boot
X.M.P: disabled
(Manually OC'ed RAM as XMP can cause problems since its presets are fixed by the MOBO, it also has save issues, and in rare cases it can negatively affect other stable components.)

(I haven't adjusted ioa/iod/sao much yet. If I were to further increase the RAM frequency beyond its limit, I'd likely adjust my S.A. voltage if it became unstable, and I'd probably keep the frequency unchanged while slightly reducing the command line timer.)
To fix it, I would increase the CPU multiplier by 100. Running Prime95 for 10 minutes alongside core temperature and CPU-Z until I crashed. Then setting the voltage to 1.25v. At 45 it crashed again. After restarting, it stabilized. Raised the multiplier to 46 and it remained stable. I could then lower the voltage to 1.24... 1.235 but encountered instability afterward.
By the way, thanks for catching that. I edited it. I was up all night reinstalling that nightmarish CPU cooler. It took a while because 'I'm right and you're wrong.' It wasn't until I reached the end that I realized my mistake. You're absolutely right, lol.
