Replacing Corsair H70...

[ricardo.vix]

Update:

NZXT Kraken X40
Corsair H100i
Thermaltake Water 2.0 PRO
NZXT Kraken X60
Thermaltake Water 2.0 Extreme

Which one is the best considering price and performance?

Remember that if I buy one of them I'll use my 2 gentle typhoon ap-15, so maybe 120mm/240mm will be better than 140mm/280mm with stock fans

I don't know if I'll buy it anymore, because I'll test my h70 first... But I would like to know anyway.

Thanks!

Hello guys!

Well, I have an Corsair H70 here and it's excelent for my system (i5 2500k@4.5Ghz).

The problem is that I'm buying a haswell combo (4670k + GA-Z87X-UD4H) and with overclock this CPU gets very hot, so I need an better cooling system.

I'll probably use my 2x Gentle Typhoon 120mm (AP-15) on it, because they must be better than stock fans.

So, I would like to know which watercooler I should buy. My preference is an 120mm, like corsair h70/h80i. I can buy a 240mm radiator, but it'll have to worth in performance and $$ (it fits easily on my cosmos II, but it's more annoying to clean and mount).

The most know are kraken x60/x40, thermaltake water 3.0 pro/performance and corsair h80i/h100i, but I don't know which one to buy or if there's better options on market.

So, which one should I buy? Why??

And really worth invest some money in one of them or the performance difference will be small compared to my h70?

Thanks!

If you're going for balls to the wall performance, the Kraken X60 or Corsair H110 are your best bet and as luck would have it, the Cosmos II does support 280mm radiators. As to whether it would be a worthy investment, try out your Corsair H70 first. If its too hot for your liking, only then consider getting a bigger AIO.

You already have decent cooling in that H70. Haswell consumes less power than Sandy Bridge so in terms of actual heat output the H70 is more than capable of dealing with Haswell. The issue with Haswell is the same as Ivy Bridge, the process scales worse with clock speed than the preceding process but ultimately the temperature of the chip is caused by a poor thermal interface between the silicon and the heat spreader. If you want to not be thermally limited on your overclock you don't need good cooling you need to delid and reduce the gap between the two as well as improving the thermal interface, or cool the processor without a lid.

There is a high chance your H70 will do just fine .. I suggest try it out first and see how much you can do with it before rushing into buying a new one ..

Okay guys, thanks!!!!

But just for curiosity, if h70 don't handle my overclock, which one should I buy??

The problem with x60 is that I won't be able to use my gentle typhoon, because it uses 120mm fans. And the h100i I've seen several people complaining that the usb and led stopped working, etc...

What about the CM Seidon XL?? H80i??

And I'll be glad if you can make any other suggestions!

One more thing...

H100i with ap-15 push and pull is much better than ap-15 in just pull or push???

Thanks!

While a h100i is certainly a better cooler it ultimately is designed for high wattage output CPUs. It wont drop the temperature of a Haswell chip very much at all in comparison to what you have because despite it being able to dissipate twice as much output as the h70 your CPU isn't really pushing a single fan slot let alone 2x 140mm slots.

Your thinking about this all wrong, you have sufficient cooling to overclock your CPU. You will be limited by the thermal interface not by your cooling system. Putting better cooling on top of that CPU doesn't really help. If you end up being thermally limited (unlikely you'll probably hit voltage and diminishing returns before voltage) then your only option is to fix the thermal interface on the CPU itself.
