Is h2o 620 enough to cool OCd 2500k?

I'm getting the new i5 3570k and i expect to overlock it to a fair 4.0 to 4.2Ghz.

Now is Antec's H2O 620 in a push pull config enough? what temps should i expect based on a the experience with the 2500k?

If it is enough to cool 95w TPD CPU it will surely do for ivy bridge 77w...

i bet you will be able to overclock that cpu higher
when overclocking use temperature monitoring tools with prim95 to stress test your system to stability
if you system hasnt crashed and your temps are below 70c you should be good

Yes the 620 in a push-pull config is fine with OC'ing a 2500K. At 4.0-4.2 GHz it runs under 30 C at idle and in the mid 50s under load.

That is a decent hyrdro cooler. I still have one that I am trying to sell on ebay. I replaced it with a noctua d14 because it looks a hell of a lot cooler and I can say that I am entirely on air. The 620 only comes with one 120mm fan so you need to get another if you want pushpull. Also, the 620 fan has one speed. The 920 comes with 2 fans and they will adjust with the cpu temps. The side of the box shows a chart that gives approx temps with an i7 990x under load. The difference between the 620 and stock intel cooler was a full 20 degrees on a 130W cpu. It should be fantastic on the 3570k.

There are better air coolers out there for the same price.

Better than the 620 or nh-d14? I am guessing you mean the 620. I paid $65 for the 620 regular price.

Other than the d14, the 620 is on par with the best coolers in that review. Do you have any specific samples in mind? I am building another system and I would be interested in a good inexpensive air cooler if it does a better job than the 620. My main reason for getting away from liquid is the fear of a leak. However remote the chance, I have way too much money in my rig to chance it.

i'm actually getting the h2o for free so that's why i'm asking if its enough, and i like the idea of silence so no air cooling systems lol... as for leaks in h20 620 noone seems to have had em so we should be safe

Silence? The 620 still comes with fans, I would replace then with some noctua or antec true quiet pro fans.

you guys and your branding fidelity...i bought 2 120mm unbranded fans from a local specilized in electronics shop they produce around 50cfm at 1200rpm while still at 12db... they costed me 2,50€ each. the only thing is that i'll have to mod em a bit because the holes for the screws dont match. so yes, silence...and cheap one.

Price and performance are one thing, notable reliability becomes a completely different animal.

The 620 is the ebst of the self contained water coolers in its price range and it's not noisy like the 920 and the Corsair H models.

But a Hyper 612 PWM or Scythe Mugen 3 will do a better job for less money

The V6 GT, Antec 920 and H70 are a bit loud at these performance levels. And you should have no trouble getting 4.4 - 4.5 GHz w/ the Kuhler 620 ....... The SCythe / Hyper 612 are good for 4.6 - 4.7 ..... Silver Arrow or Phanteks ..... 4.8 - 5.0 . Of course that's with regard to thermal limitations, electronically, it's luck of the draw on how good an over clocker your CPU will be

Expectations regarding K series overclocking in general and on ASUS P67 motherboardsPrior to the recommendations on overclocking the K series, I am outlining our results to set expectations.
The results below are based on the range of the CPU turbo multiplier when overclocking.
Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

guess the 620 is the way to go

khuler outways the cooler master hyper 612 i thought it would some guys really need to look into benchmarks that arnt stock fan speeds, erm and its cheaper too
