Freedomdwarf,
I think these are typical results. Remember that I am using the max temperature recorded under prime 95 tests in the statements. The average temperature is lower than that.
My goal was to see if I could gain 200-400MHz in overclocking with more cooling. But I guess the stability of the core i7 950 goes downhill after 4.14GHz. Hence. the only benefit I have now is that my fan speeds can be much lower for the same overclocking.
At the end of the day, the H50 is still a great choice because of price. You could also buy better fans with the extra money to lower the noise levels. The stock H80 fans are much louder then my H50.
The other thing I did not like about the H80 is that I dont have control of the fan speeds like the H50.
Its a good cooling system but not a night and day comparison.

@freedomdwarf
the 1000+ psu's do have a lot of hardware in them, so finding space for a large fan would be a problem - like the antec's with the fan bolted on outside 
the modular ones have more choice of ones with larger fans though
I've only got a 750 in here and it's never had a problem, but i'm not running multiple gaming graphics cards, just an old 7800gt and 7 hard drives

@ evropej -
I agree, the H50 is good value for money and I did consider getting one. The thing that swayed me towards the H80 was the ability to switch cooling profiles at the press of a button (which I did yesterday), the fact that the fans are controlled from the cooling block itself (which are PWM controllers) so I didn't need to use up two PWM fan headers from my motherboard, and the fact that the mounting was infinitely better than the earlier models and the Antec Kühler H20 option.
There's no reason why you can't put the fans onto your motherboard PWM headers so you have more control of their speed if you have the software to control them outside of the BIOS.
I didn't choose the water-cooling option for over-clocking reasons. I chose it because of a heat problem I was having with the stock air cooler that the CPU came with. I do over-clock slightly but as was mentioned by dloneranger earlier in this thread, you are better off all round to buy a faster CPU than to over-clock the crap out of it and have to fit better cooling to compensate for the over-clocking. Over-clocking is fraught with problems and risks burning out your CPU (or something else) as there isn't the leeway for the slightest hiccup to happen and I don't go that route - its a mugs game.
@ dloneranger -
I used to have an 850W PSU in here when I first built this rig and I noticed that I often failed to get top speed when trying to burn DVD's whilst I was rendering or the burn wasn't always 100% successful and sometimes my nVidia card complained about low power levels. I have retired that PSU to a lesser PIII machine that also has a number of hard drives and also two burners (well, 1x DVD burner and 1x DVD Combo).
Since uprating the PSU to 1,000 watts I can now burn at top speed with both burners, sometimes in parallel, without a failure and I can still be rendering in the background at the same time. Also, since uprating the PSU my nVidia card hasn't complained once! I'm fairly sure in saying that in general, Sata drives seem to use less power than their IDE counterparts. So I think my main problem on the power front was what the processor was pulling under load together with burning DVD's and my nVidia card requirements.
I know it was a borderline power problem because I only had to unplug one of the case fans (any one) and I never had a problem. That tells me the PSU was struggling to supply all the power I was asking of it - hence the upgrade and why those lower-rated PSU's were not an option for me.

block at 180
vcore at 1.275
with H50 cooler runs just great at 4.14GHz on core i7 950
This is well within the specifications of intel for temperature and voltage
You can even lower the vcore a bit more to get temps which are always below 70C
There is of course a risk but then again, if someone can afford $200 dollars of cooling hardware, they can afford $200 for new cpu lol |

The Corsair H80 is half the cost of a new CPU - in some cases, less than half.

Cooler, fans, thermal compound is equal to new processor such as core i5 or core i7. I believe I see the 950 for 180 on sale at times.
Remember, these new cores are designed to run higher and they do with their wimpy stock cooling systems. The new cooling system allows you to run the core continuously. You can go overboard of course and stress things as well. In most cases you can easily overclock 30%.
To prove this to yourself, install your stock fan and run prime 95 and watch the temperatures. Intel ships them this way lol. |

H80: $101.99. (newegg)
Arctic Thermal paste (if you don't use the pre-applied TIM): $5.95. (newegg)
Fans: supplied (free). Don't need any extra fans.
H80 total price = $101.99 ($107.94 with paste)
Intel Core i7-950 Bloomfield 3.06GHz: $259.99 (newegg)
i7 is 2.4x the price of the H80  So where's your logic??
| QUOTE | | In most cases you can easily overclock 30% |
??? A lot will depend on your hardware and motherboard combination as well as your CPU.
Some will over-clock well, others won't.
I have never managed to get anywhere near that 30% figure... ever, and none of my friends have either.
I know we aren't OC techies but that figure is exaggerated for sure - especially if you include 'most' and 'easily' in that statement.
Most of my over-clocks have been less than 5% before it becomes unstable but I did manage almost 12% once and that CPU/mobo combo only lasted a few months before it died. In most cases, Windows complains and shuts down or won't boot in the first place.
I can't run Prime95 with the stock cooler - it shuts down within 5 seconds with an over-heat!
That's why I had to find a cooling solution.

Hard to believe this since I have tested the 30% overclocking on four processors already ( 920 950 950 and 2600 ). By default these guys are stable over their rated frequency with boost feature which is built in and enabled by default. What processor are you talking about or have tested? |

Those all look to be i-series CPU's - I don't have any of those.
I have tested -
Intel 500MHz Slot1
Intel 650, 700, 733, Celeron 800, 833, Celeron 900, 1000, 1.13GHz
Athlon MP1500, MP1800, MP2200
Intel Core2 8400.
That's all I can remember off the top of my head at the mo but there's quite a few others too.
All been on assorted different motherboards including Abit, Dell, MSI, GigaByte etc.
Most of my PC's are low-end, I only have 1 half-decent P4.

This explains it. Prior to core 2 duo, it was a pissing contest for MHz which means the cores were running at absolutely maximum frequency. AMD was notorious for shipping processors which were overclocked. Word of advice, stay away from Celeron processors lol.
Sometimes they have them even lower. Anyway, I would get the core i5 if I had a choice since hyper threading is a complete waste.

Those metal glues are strong when used and applied correctly. Pc case people tend not to sit or stand on them, they usually just sit there, case stress? I wrote the above for everyone who maybe take a look. Expand them further with their own idea for other projects. |

@ vdub -
I know several people that have done mods to their case and used metal paste to repair them afterwards (and they always look awful too!). Those products are ok until you move the case - then the repairs tend to crack or break open. Considering two of those people are bodyshop repair specialists they are well used to using these products and in both situations they ended up having to buy a new case because the paste is just not strong enough!
