H80 fans change them or keep them

Just to confirm what chip are you going to be overclocking? I had it in my head you were getting a 2500k but reading over the thread you don't say anything about it, either that or I'm confusing my self again haha.

4.6 - 4.7 Should be easily done with 1.38v, on the majority of chips going 4.8 and beyond is where it gets tricky. I didn't try 4.6, my OC history went 4.3/4/5/7/8, but I do remember having 4.5 stable at around 1.29v and could have gone lower.

I would advise to begin with just up the multi and leave the voltages on auto and keep an eye on what kind of voltage each clock is using, auto will also feed more voltage than required but it will give you a kind of 'max stable voltage' reading, something that you know it will work at and can work back from.
 
Haha I thought so just had a major moment of doubt in my mind!

So yeah, auto and see what the motherboard is feeding the chip, and then manual from there and head south until unstable :)
 
Ideally you want a fair few hours of prime, but its upto your self really, for 1.312v I did an hour of prime followed by 4 hours of gaming, in the real world no game is going to put as much strain on the processor as prime will.

You will find out if its unstable as you will get a BSOD, if that happens put the vcore up a little and try again until no more BSOD
 
i would not leave your voltages on stock , the auto overclock will pump way to high a voltage through your chip.
I tend to prime for around 10 mins each time till i get to a level iam happy with then prime for about 6-11 hours depending how much time I have :)
 
The Asaka fans are not any cooler than the Corsair ones.

The corsair fans are a standard (non-gimmicky) design and they spin at 2500rpm max.

The Asaka fans spin a load of ******** and turn at 1900rpm.

Here's a review of a load of 120mm fans including... an Akasa Viper: http://www.xbitlabs.com/articles/coolers/display/120mm-fan-roundup-2.html

It claims 83cfm? It does 31cfm max in the test vs the others compared. It claims 29Db and it does 50Db.

It's a VERY average fan.

So given that it's an average fan spinning at 1900rpm vs another average fan spinning at 2500rpm, it's going to lose at cooling. The 2500rpm fan will be louder at max speed however.

Reviews can claim they are as average as they like, my load temps are about the same if not lower and the noise difference is certainly noticeable. Vipers are pretty damn quiet under 80%.

I'm not saying they blow 83cfm as akasa do, but they are more than upto the job.
 
I wouldn't say so, but see how you like them, if you spent all of your time reading so called 'reviews' you wouldn't buy anything, for every positive review there are going to be negative ones. fact. Which is the beauty of a forum like this, you get independent reviews from the people who use them every day.
 
i appreciate that antec and corsair are in different leagues (but the kuhler h20 is actually made up from the same components that are used in the h50 and h60 because antec used the same supplier) and i have to say, the stock fan is HORRIBLE!

i'm running in push-pull with a lian li fan on maximum, and the antec fan on speed 6 (out of 9) otherwise it makes that typical 'cheap fan whine'
 
my temps are 29*c idle and 58*c under load on a cool day, and 34*c idle and 62*c under load on a warmer day (if anyone was interested)

On the contrary.

As a result of reading quite a few fan reviews I've purchased four 120mm Gentle Typhoon 1450rpm fans.

Why?

Because the GTs are highly regarded by a vast number of people who have used them and in a review with live recording with sound between my (average) Enermax Magmas and Gentle Typhoons I can see and compare with my ears that for the same volume of air being pushed through a radiator the Gentle Typhoons will be able to do it 7dB quieter and use 1/3 of the energy.

The exact figures are on the measurement devices on the review recordings in case you're wondering if I can hear an exact dB number.

So when they arrive I'm going to record my current rig, at a fixed distance, replace the EMs with GTs, record again. That plus whatever I reckon about the tone the fans produce in the case will determine if I keep them :)

Reviews are a tool, but personal experience decides it.


This is the particular review thread I'm taking note of because of the reviewers frankly obsessive steps to be fair between the fans and how its recorded: http://www.xtremesystems.org/forums...0mm-Fan-Testing-on-an-MCR120-Radiator-Round-6

Yes but user reviews aren't comparing the product to others using the exact same test configuration so they end up being more subjective than anything. Sure they might be good but the xbit review highlights that there are better fans out there.
 
Got my rig up and running and with my H80:D
Should i start overclocking very soon or should i just wait a 24hrs or something. So the paste and the H80 have settled.
I also have it running at max (3 white squares) and it loud at all really, and when i start gaming i wont hear wiith my headphones.
