Anyway I've always used aircoolers, but I'll be buying a piledriver when it comes out and I want some good cooler to push it to around 4-5ghz.
I asked around tomshardware and everyone says bad about closed loop coolers... One guy even said the leak chance was around 20%... Can you guys give me some advice on this as I am a bit afraid of leaks after that.
Also I live in the south of spain, most of the time, and it's fairly hot during summer, today was around 38-40C, do you guys thing the H70 is a good buy or should I try and go for a H80? (I have a HAF X)
Hi. I'm not privy to the manufacturers failure rates, but most consumer goods have about a 6% failure rate. I would suppose that closed loop water coolers are no different. However, it's likely only a percentage of the failures actually leak. I'm pretty sure I can count on one hand the number of times I have seen people complaining about leaking with the Corsair coolers. In each case, Corsair offered to replace any damaged equipment if the leak was caused by a manufacturing defect. In one case, a guy had a leak and Corsair actually sent him better parts than what he had to begin with.
The Hydro Series coolers (with the exception of the H40) all have 5-year warranties. I'm a member at Tom's too, and in general their a pretty good bunch of guys over there, but I do know there's a few of them who have no clue when it comes to closed loop water coolers. I bet, to a man, all the guys speaking out against them haven't even tried one. If you look around on ocn, in the threads for different cases and builds you'll see tons of water coolers. Almost as many as air coolers. This is the right place to ask, because many of the people here have experience with them.
The H70 Core is not a bad cooler, even more so because you're not paying for fans and you can select your own. There's no doubt though that the H80 is a little better cooler as it has a newer pump design. I would expect the H80 to perform about (roughly) 4-5c better than the H70 (I fully documented my H70 to H100 switch last year, and I got about 7c better temps across all four cores. Since the H80 is pretty close to the H100, I would expect it to be about 5c better than the H70 under the same circumstances). That was with a Core 2 Quad 2.5GHz overclocked to 3.3GHz. Your results will vary with different CPUs.

I have both, the fan connecter and molex connecter plugged in. Should I have both plugged? I know you guys are Corsair Reps but any help is greatly appreciated.
P.S. I ran AIDA64 stress test to see if the fans would ramp up and they never did, my temps reached 70C.
Maybe you should email Corsair George ( email@example.com ). It's really unfortunate to get two units in a row with a bad block/fan controller. Have you thought about using third party fan controller instead of the controller in the block? Have you checked to see if your motherboard will support controlling 3-pin fans? If so, you can plug them into your motherboard. Some motherboards now have two cpu_fan headers but if yours doesn't you may need a splitter of some kind. Unfortunately, other than Corsair's reset instructions, I don't know of any way to get a failed block/fan controller to work.
The Molex connector is for the voltage going to the pump and the fans. The small connector you plug into the CPU_FAN header is the RPM signal from the pump. This lets you see the RPM the pump is running at in BIOS or with software, while also preventing a possible CPU_FAN error some motherboards will get if there is no CPU_FAN RPM signal.
I would recommend talking to Corsair George first though. He may have better advice or a better solution. If you find the only option for you is to send it away again, think about using a different method to control your fans. You do have a few other options.

- Purchase a fan controller. They're fairly inexpensive and work pretty good. Unfortunately you'll have to manually control your fans (some people like this).
- Check and see if your motherboard will support controlling 3-pin fans. If it will, you can use it to control your cpu cooler fans. Check your manual. You may need a splitter.
- If your motherboard will not control 3-pin fans, you can always purchase some PWM fans and use a PWM splitter to control them from your CPU_FAN header on your motherboard. Plug your small pump RPM connector into a CASE_FAN or PSU_FAN header.
- Plug direct into molex and let them run at 100% all the time. Some people like this, personally I don't but it's still an option.
