CPU cooling advise please
CPU cooling advise please
I discovered a method to monitor CPU and GPU temps, and noticed my CPU hits around 100°C during VR sessions (Valve Index, Population One). My system runs an Intel Core 7i 10th Gen. I’m still learning about PC components, but my dad gave me a prebuilt unit two years ago that’s performing well! Since then, I’ve upgraded to a 3060 Ti and added a hard drive. There are no extra fans, GPU fans, or any fans near the CPU.
1) How intense is 100°C?
2) Can I lower CPU load or improve cooling until better options appear?
3) What’s the best first move to boost cooling?
It's reaching its thermal limit, which means it's slowing down to operate at 100°C or below. This results in reduced performance. 2) It's not really effective. 3) Clear out the system—use a PC blower or a compressor at around 2-3 bar pressure and blow the unit out if you haven't already since installation. Removing a lot of dust will make a big difference. Keep the fans stationary during this process so they don’t spin too fast. You can use a paintbrush to dislodge stubborn dust. Also, take a photo of the interior to help identify your cooling setup and case condition.
Here is a picture, let me know if u need a different angle. It is a basic dell prebuilt. I have some cans of pressurized air i can gently blow stuff out and hold fans and test again!
The Dell G5 gaming desktop works well, but the cooler alone won’t handle an i7 10700. The good news is it fits standard coolers without much trouble. You can easily install any 92mm model and expect better temperatures. The setup will be a challenge, but definitely achievable. Plus, you get the premium 2 sticks of RAM from Dell—rare and worth it. As for CPU temps, Dell’s budget models tend to hit their limits right out of the box, so you’ll likely see them running at maximum temperature.
Sure! Your dad can definitely assist with the installation. Just to confirm, we're referring to the fan on the CPU, correct? Thanks for your patience—learning this takes time. Running it this way has been ongoing for more than two years; you might want to consider whether it could affect its lifespan.
You're referring to the whole cooler setup. Improving the fan won't help much. Your system has been in damage control mode for the entire time, and it's managed to stay within safe limits by slowing down itself to avoid further harm. A Hyper 410 from Cooler Master (or 412 or similar) works fine. https://www.dell.com/community/Inspiron-...-p/7385750 A person is making changes to an older model of your PC, but everything remains the same except the front plastic part.
We chose Noctua and checked their specs and installation videos. We placed the NH-U9S Chromax black and added a 120mm intake fan and a 90mm exhaust fan. I also ordered a 3D-printed mount for the front, thinking we need to remove the existing hard drive bracket, which isn’t designed for a 120mm fan. Watching two installation videos gave me confidence it should work.
Yup, really nothing quite fits. That fan won’t make much difference, though a bit of airflow is welcome. You might have chosen a P12 Max instead. It offers similar performance to a Noctua premium model but at a lower cost. The Noctua version also works well, but I usually don’t suggest it because of the price. The H410 would have been acceptable too. But the U9 is definitely the top pick right now (there’s another odd cooler out there, but it’s complicated to install :p).
By the way, a lesson for the future: make your own PC or pick something prebuilt if you get one. Even if you never upgrade, being able to find non-brand parts is valuable. Also, keeping value intact is important—Dell’s current reputation is poor, and they’re hard to resell. That’s why I run one of these as a game host server; I got an i5 10600 for 250 € a year ago.
Plan is to construct my own setup whenever the funds permit. My next aim is to acquire a fresh case within about a year, after which I and my dad will finalize a new build (motherboard, power supply, etc.). My dad becomes very enthusiastic quickly, which explains why I have this PC and Index and not a $200 quest... I just asked for an Oculus Quest 2.5 years ago and this is what I received! haha. I had no prior knowledge of PCs (still don’t) and my dad wanted a solid, reliable machine, especially since I’m inexperienced—until I realized some things later.
It seems the Dell model in question has a highly customized motherboard that doesn’t match any standard configuration. The PSU also doesn’t fit typical sizes, which is why they’re left as-is. There are built-in sensors that block boot if they’re missing, making it aimed at specific users. Over time, the thermal paste can dry out or become dusty, causing performance issues and forcing replacements after a few years.
