I recently posted about upgrading my Dell's GPU. However, before I do that I need to bring my crazy system temperatures down.

I have a Dell XPS 8500 with:

256 GB SSD
2TB HDD
24 GB RAM
I7-3770 3.4 GHz
GTX 660 (1.5 GB GDDR5)
460W PSU (I think it's a proprietary Dell PSU)

During gaming and rendering my CPU reaches maximum temperatures of 80 degrees Celsius and my GPU reaches 100 degrees Celsius, (even after extensively cleaning dust).

I am looking for ways to get my computer MUCH, MUCH cooler as it is way above dangerous levels right now. Even at idle my GPU hangs around 60 and my CPU near 50.

I have considered installing a Cooler Master Hyper 212 EVO - CPU Cooler and applying new Arctic Silver 5 Thermal Paste but I don't know if the meager Dell PSU would be okay with a new cooler that might draw more power than whatever cheap cooler is in there.

Surprisingly the system only came with one fan (rear exhaust). That is probably causing poor airflow right? I would feel better with one or two more fans in there, especially a front intake fan. Sounds like Noctuas are a safe bet?

So, my total question is: can I safely upgrade my CPU cooler and/or put in new fan(s) with my poor little 460W Dell PSU?

Thanks for your time.

Lol fans and cpu coolers don't draw that much power. You should be fine considering that youve already run a 660 on that without problems. The NF-F12 from Noctua is a very low power fan (0.5w) and it probably the best fan you can buy. Get those if you need new fans.

Also you should make sure you have positive air pressure for the best cooling. With that 1 exhaust fan, add 2 intake fans so that you have more cool air entering the case. You'll want to replace that shoddy case fan with something like an NF-F12.

I had a similar issue with my Fx-8350 with stock cooling in a poorly ventilated case. Installing the Hyper 212 Evo gave me an extra 15C of headroom, going from topping out after about an hour of gaming to staying stable under the thermal ceiling even after a 5 hour prime-95 test. Granted, i'm still moving to a new case when i get the budget, but the hyper 212 will definitely help with the CPU.

Are you experiencing any system instability? You might actually just have faulty temp sensors. But it isnt a bad idea to get a hyper 212 and a couple new case fans regardless.

The Hyper 212 is an amazing CPU cooler put it and your CPU overheating problems should be gone. The GPU though is a bit tricky. I would advice to use EVGA Precision X to ramp up the fan speeds a bit, and buying some more good fans for better airflow. I recommend buying some Corsair AF 120 fans for the case. They are really good case fans and quiet. That PSU needs to go. Get a high quality PSU, the Corsair CS 550M is a really good high quality PSU. You could also go with the Corsair RM 550, both perform equally, though the RM 550 is fully modular and the CS 550M only Semi-Modular but is a bit smaller. If all fails, get a new high quality case with a lot better airflow

I'd suggest moving components into new case maybe and getting more fans and get a noctua dh 14?

A Noctua NH D14 is not needed for a locked CPU like his, the CM Hyper 212 EVO will do just fine, my main concern is PSU

Modular power supplies are inherently larger than their non-modular counterparts, no?
