Stock coolers are amazing... At least this 1 I got on a PC I got from school for free :)
----------------------------------------Intel Core 2 Duo @ 2.53 GHz, 24/7 (minus auto restarts for updates) @100%, max 47-50°C It uses the 250 GB HDD from my old laptop, and THAT uses an Ubuntu live session with its Single Core Celeron also going 24/7. It gets up to 60-62°C. To save on bandwidth channels, I linked it to the core 2 duo via Ethernet, and it all works well. And those 12 other devices... 2 are on family PCs (parents let me don't worry), and 1 on my current laptop. They all run @ 35% on all cores when idle. The rest are me trying it on my tablet, virtual machines, etc. So my question is... What's your setup? Cheers!  |

So my question is... What's your setup? Cheers! all computers run 100%, even in Croatia's 38°C in Zagreb! all CPUs work on WCG...while all GPUs work on SETi@home ! all laptops work with TThrottle , set to 80-85% of Tjunc of CPU & GPU... all Androids with single or dual cores work on 100%... all quad-core Androids work on 3/4 (75%) of CPU time or CPU cores...still trying to find a best setup!  |

I haven't tested many CPU's older than SandyBridge for stock cooler efficiency but certainly the i3/i5/i7 Sandybridge and later CPU's can run 100% on stock Intel air coolers, assuming there is some active way of getting the heat out of the case.
----------------------------------------The downsides are noise from the CPU and case fans, one reason why the liquid-cool boys like to add more watery complications or giant vertical air coolers to their machines. I have a new Haswell box here with a stock Intel air cooler on a G3258 CPU, it runs 100 per cent in a mini-ITX case at around 60C with an ambient air temp of 23C. Noise is 31dBA, with two case fans and a PSU fan I did test PC cases for a company; the best performers for noise-free 100 per cent running with i7's were the Fractal Design R4 Define, which has noise-absorbant panels and a solid front 'door', and the Cooler Master Silencio or their very cheap mesh-front cases. The Cooler Master Elite Mini-ITX cases are also surprisingly quiet. The simplest method of 'sliencing' air cooled boxes was to add dual 120mm exhaust fans on fan speed controllers to get the hot air out the box so that the case interior is at or near ambient temps. with minimum noise outputs. The BitFenix Prodigy M-ITX and M-ATX cases are also good, until you fit the acrylic window side panel which blocks off most of the air intake. Again, they can take dual 120mm exhaust fans on speed controllers, so the stock cooler works at 100 per cent. 'Quiet Running' we defined as 30dBA, 1 meter from the PC case. You can try this with a smartphone noise meter if you have a quiet room. The human ear is sensitive to pitch variations on equipment fans, so fine tuning CPU fan and case fan speeds not to vary gets the perceived 'noise' levels down. The current main crunchbox here is an 17-2600K running at 100 per cent, on air, built especially for WCG. It's in a BitFenix Prodigy case with 1 x120mm exhaust fan and an external dust filter on the side panel.  [Edit 2 times, last edit by Hardnews at Sep 24, 2015 7:52:16 AM] |

I built a system with an AMD FX8370E and the stock cooler was struggling with 75% of the CPU being used for WCG (6 of 8 threads). I upgraded to a cooler master tx3 cpu cooler and temps and noise dropped significantly.
After recent experiences with liquid, I think I'll stay away. I inherited a bunch of liquid cooled systems for use at work. The CPUs run full throttle, and the cooling pumps fail rather quickly. I know there is different quality of products out there, and the ones I have are probably not great quality. But after seeing where some have actually ruptured and leaked coolant all over the motherboard, frying it, I'll just stick with air cooling. As a side note, I recently picked up one of these for work, it is equipped with 8 GTX TitanX cards   |

what's ur work? I play around a little here and there with decryption stuff. Its running ubuntu and a nice little command line program called hashcat. Cooling on this thing is phenomenal. With all 8 GPUs at 98-100% utilization, they are running about 68-71C in a 20-22C ambient temp and the fans on the cards are barely hitting 30% fan speeds. |

 "G750JS" - i7 4700HQ - GTX870M - 16GB RAM - 240GB SSD - 1TB HDD Temp gets up to 80c on both CPU and GPU when @ 100% so bit crispy but seems to be stable enough. The keyboard surface and below the laptop is always cool to the touch though, all the heat comes out the vents at the back. |
