i5-2500k Realistic WC Temps

post #1 of 8
Thread Starter 
I'm about to take the plunge into a WC setup with an i5-2500k, and I'd like to know, realisitically -from all of you OCNers who have these setups- is it worth it? It'd be my first water cooled setup, so that means an initial plunge of about $400-500.

After perusing forums (this, techpowerup, etc...), I understand because of the lower thermal output of sandy bridge that WC doesn't make THAT much of a difference. Realistically, for an i5-2500k, is there a noticeable difference in performance between air cooling and water cooling?

Thanks in advance

Depends how hard you're wanting to push your processor;
Depends how high a temperature you're willing to live with;
Depends on the noise you're willing to live with;

To be honest a Noctua D-14 or Thermalright Silver Arrow etc will cool the 2500k just fine given you have adequate case air-flow.

But. . .



Water is so cool *drools*



Have you looked at the XSPC Rasa or Swiftech Apogee XT "water cooling kits"?
Very cheap way to get into water cooling (<$300 i think) which you can easily build onto in the future.

HUGE difference, at 5ghz i peak 60C full load with 2 GPUs in my loop.

I think it is worth it, and you will see a difference. If you add GPU(s) to the loop, even more so.

I don't think it is worth it considering when you need that type of cooling you are putting (arguably) some serious voltage on your chip.
Personally I think were water cooling shines is multi GPU setups, but its a cool hobby if you just want another money sink, otherwise, save your $ and save your processor.

Realistically, there is no need for a 2500k past 4.5ghz, which is easily achievable with good temps on a D14.

Water cooler is the way to go if you going to overlock... If you going just very little overlock then just go with any good air cooler or even a beginner water cooler like H50 or H70 and you be set.

Unlike me I been through the best air and then jump to the H70 and now ending up with the XSPC RASA Kit best route to go if you going for water just jump straight into an XSPC kit depends on the case you have the bigger the radiator the better your temp will be...

at 5.0ghz 1.45v on my Venomous X the highest core was 77C Prime Blend Test for 12 hours. So in real world usage at 5.0ghz 24/7 the highest core won't reach over 70C and that is well below the margin of max temp.

SNB chips run a lot cooler you really don't need to go water to achieve low temps, it boils down to the voltage, the right SNB Chip, and right heatsink.

I myself will go WC again once I find the right 2600k chip

I hope my project build can give you some ideas.
Also be sure to take a look at the "sandy stabe club" for temps/voltage database of sandybridge overclocks. Both links can found in my sig.
