    Ya i have the H50 I went from h50 to H70 And not That Impressed so i went back to the H50 I have a i7 OC to 4.4
    The only thing i might see a little Difference is the 2 to 3 Deg Difference that's About it Not that much move for the price!
     
  2. I tell you what, I ran my fans in the h70 the way kyle has his, blowing air out of the case, but now since all the snow is here and my heating is on all day my temps were starting to get to where I didnt like them to be.

    So yesterday I replaced the fans to sucking in instead of blowing out and even though it means cleaning the inside of the case more often for dust, their has been a remarkable temp change, so I would advise everyone who uses the h70 to use the fans as directed instead of using them to suck hot air out of the case.

    I see about the same performance intaking or exhausting. I have a lot of intake fans though, that might make a difference?
     
  4. I see about a good 8/9oC difference, simply by using the fans as directed.

    I have on my case just one 80mm door fan blowing in, no other fans except the psu/vid card/and 2 corsair h70s ones.

    Installed my H70 yesterday and I'm doing 3-4C cooler at idle as well as 3-4C cooler at full load (IntelBurnTest) compared to my Scythe Yasya so it seems on par with what I expected to get after examining the [H] benchmarks in the article. I installed it with Noctua NT-H1 thinly spread across the CPU and I cleaned the original paste from the H70.

    I initially installed it with the fans blowing out of the case and wasn't too happy with the temps but I then changed the fans to the way the instructions said and temps dropped. Since my case (Antec Nine Hundred Two) has a big exhaust fan at the top I figure this shouldn't be a problem, only downside being that more dust will enter the case.

    [​IMG]

    Gigabyte utility is shown for voltage reference; those are the voltages as they are set in the BIOS. CPU is at 1.325V. Max temps were hit running IntelBurnTest. With Scythe Yasya it hit 80C.

    This is my experience with the Corsair H70 which is somewhat O/T considering other modifications have been included.

    Installed the H70 with the included Corsair fans exactly the way Corsair recommended and wasn't all that impressed with the initial results when compared to my Thermalright Ultra 120 with a single fan. CPU temperature only dropped down 2c at idle and just under 2c loaded. Replacing both Corsair fans with 2 x Yate Loon 12SM12 fans didn't achieve any better results but did lower the noise level down a few dB.

    Swapped-out the front Corsair fan with a Skythe DFS123812H-3000 which is almost as noisy as a couple of over-excited kids at Christmas time :p Temperatures dropped another 3 to 4c, both idle and loaded. Pic for reference.

    [​IMG]

    The biggest issue I experienced with Corsair's recommended mounting position is the CPU power regulators weren't getting adequate cooling, at least in my CoolerMaster ATSC 840. Stuck a finger back under the radiator during a round of IBT and the heatsink covering the MOSFETs was very hot to the touch. A re-mount was in-order.

    To solve this, I removed the 2 x 230mm fans from the top of the CM ATSC 840 and installed the 120mm fan / radiator brackets that were included with the case. I had originally wanted to mount the H70 further forward but the hoses were about 3" too short to clear the Corsair Airflow RAM cooler. So, I reversed 2 of the brackets and mounted the H70 towards the top-middle of the case. Pic for reference.

    [​IMG]

    With the H70 re-mounted and an additional 120mm fan in-place the CPU power regulators weren't getting as hot as before during IBT, but were still warm. I happened to have an Asus VRM cooler available so it was stuck on the rear facing VRM heatsink / heatpipe for additional cooling. Although, with the additional airflow going through the case (1 rear exhaust, all others intake) I'm not exactly sure how much good it is doing.

    With this new configuration, CPU temps are now roughly 9c cooler during load (75c vs. 84c) and run about 34c idle with the i7 965 Extreme running at 3.88Ghz. Of course, me not being content with having enough airflow I zip-tied one of the 230mm CM fans to the upper support bracket just below the top of the case. Now we're talking. :D

    [​IMG]

    Overall, I'm content with Corsair's H70 cooling capabilities now that the fans have been replaced with some that have a little more 'kick'. The H70 would definitely be a good choice for someone starting out with water cooling, provided the person doesn't mind the fan noise. Of course, noise can be lowered by replacing the fans. The H70 fairly easy to install and performs fairly well. I'll definitely recommend the kit over other solutions.

    I also did some testing with the H50 and found if the pull fan runs at a little bit higher speed than the push fan it helps cool it a bit more,plus it seems to cut down the noise..its like with 2 fans running the same speed air builds up in between and the fans made this hum type noise so I have a faster pull fan and it seems to work better..IMO

    Other reviewers should take note and test heatsinks inside of a case. :)

    I seen couple of mods on the H50 that seems to help the cooling but for the price may as well go with low cost kit (Rasa 750 RS240 WaterCooling Kit)

    I tried something new,I have a GTX 580 and a 9800X2 all folding in my rig and the hot air coming out the back is hot coming from them two cards,I moved the radiator right under my DVD drives with same fan config pulling air through the front vents and added a fan to the back of the case blowing out and I dropped 8 degrees C.
    All that hot air was being sucked back through the radiator..
    Going to make something to mount it if I cant find something..It even looks as though it belongs there:)

    So I'm thinking of getting the H70. Here's my story tell e what you think.

    CM 690 II advanced case with I7 930 OC to 4 GHz running SLI GTX 460's. Hyper 212 CPU cooler.

    Idle temps @ high 40's to low 50's. Load temps get to @ low to mid 80's. This is running F@H bigadv unit plus 2 x GPU units)

    140mm front intake, 140mm side intake, rear 120 mm exhaust, top 140mm exhaust.

    Now corsair recommends rear intake on this but let me say the back of my case is HOT. I'd put more fans but do to location and the size of the Hyper there is no room for more, plus there is a 2nd PC folding 24x7 in the same area both exhausting to the back of the desk where the PC's are.

    I'm thinking of putting the H70 in the front of the case to try and use that cooler air just not sure it will reach, if it does not any other suggestions?

    thanks

    I went with the H50 only because of sound levels. Thing runs pretty quiet...

    When I was installing the H70 I thought about putting it in the unused drive bay area up front but the lines were kinda short. Are you guys able to get it all the way up front or is just just hanging in the bay there? (depending on your case, of course).

    I might try it, I'd just have to loosen the cooler from the CPU to rotate it to get the lines to reach further. I could probably zip tie it into the drive bay.

    Bah, it won't fit in the drivebay area on the Antec NineHundred Two.

    Do you guys have any suggestions on how the radiator and the block should be positioned in regards to gravity or does it matter?

    That's disheartening. I have a 900 and was thinking about this cooler for my next build and was considering sticking it up front in all that unused drive bay space.

    I currently have a TRUE120 that has done a stellar job of keeping my Q6600 cool at 3.4ghz. Assuming my temp readings are accurate, I idle at 30C or less, and when gaming, temps tend to stay in the 50s. Admittedly, I have two Scythe 3000rpm Ultra Kaze fans on the TRUE, in push/pull config, but they are on a fan controller and set as low as I can possibly get them. The setup is incredibly quiet.

    Now that Sandy Bridge is out, I've been contemplating my next build and this cooler looked great, but I really don't like the idea of pulling air from the rear inward. I know that, technically, my TRUE is expelling hot air back into the case, but in practice, there is very little space between the pulling fan of the TRUE and the rear exhaust fan from 900. Heck, at higher speeds, the Scythe fan will push enough air to spin the rear case fan on its own :p

    EDIT: Perhaps, maybe, with one fan, or two slim ones, you could attach it to the side panel? I don't know if there would be enough clearance between the rad and GPU in that case. If it did work, though, it wouldn't be so odd to have it drawing air in.

    Anyone out there with the Antec 900 coming up with something better than pulling in air from the rear, where my PSU and GPU are blowing all of their hot air?

    I don't think gravity matters,ive seen them suspended on small bungey straps and even blowing out on top of the case..

    tried to put mine up front but it would not fit in the drive bay with the Blu-Ray drive there. Put it in back doing exhaust and it seems to be running nice. Gave me about 7-8 degree drop. Stock fans are loud though so I might swap out for some quieter ones.

    Got the H70 for xmas, and I really like it so far. Only negative that I have found is that the tubing is STIFF. My rig idles at 30c and has never gone over 50 w/Orthos running for 30 mins. Unlike [H]'s review, I have my fans blowing out. I don't have a top exhaust (working on that). I had a TRUE on the system before and idle temps were about the same, but under Orthos, i was up to 54c. So, there is an improvement. I think that I might gain about 1c with the fans blowing in.

    So what fans are best to pair with the H70 for a good performance/quiet setup?

    Edit: after some recommendations in another thread, I got two Gentle Typhoon 1850's.

    Even better than arctic silver 5? Because most of the time other tell me to drop new thermal on cooler.

    System is in my sig.. My i7-2600 sits around 26C when I'm just surfing the net, word processing, email, basically idling.

    Is that too high?

    Oh yeah. You should definitely be idling at least 10 degrees below the room's ambient temperature. :p

    [EDIT1] I've placed an order for my H70 today and expect it to arrive by the end of the week. I'll post the results regarding my i7 870. It's on sale in Canada for 75$ + 10$ shipping until Feb. 9th, but you'll have to PM me for the link as it's being filtered out.
    [EDIT2] Puralotor guy has came and gone today. It got here FAST, but I'll only be able to pick it up tomorrow. Damn.
    [EDIT3] Installed, writing a short review. Long story short, I'm up 600mhz and 10c under.

    I've had my H70 for a few months. I do agree with the stiff tubes bit. I feel like I'm about to break it everytime I try and move the tubes around.

    Someone asked about the thermalpaste on it; its alright. I used it for several months with no problems. I moved some stuff around and replace it with some MX-2. The paste that came with it felt very thick to me, like they put way more than they needed to on it. I got around a 2-3c idle temperature drop by changing the paste.

    I'm running it with an i5 760 at 4ghz. Idle I get around 25-30c (depending on room temp), compared to 45c with the stock cooler at idle speeds. Full load with Prime95 I max out at around 55/56c.

    I've replaced stock H70 fans for Ultra Kaze 2000 for better static pressure. Now I am wonder if adding the duct (25mm) after pushing fan will further increase performance.
    Any thoughts?

    Has anyone installed one of these on a Corsair 600T case? I'm looking to buy one today and was wondering where I should put the radiator/fans for this case.

    The only real place to install a H70 on a 600T is on the rear exhaust opening. The front and top mounted 200mm fans block any other area you would have to install it. Just remove the stock 120mm fan from the rear and replace it with the H70 fans/radiator.

    Has anyone bothered to try to mount this in a blowhole fashion... Suck air out of the case through the top and through the radiator?

    Reason I'm thinking this may be a good way is due to the fact that my Video card ports hot air out, as does my power supply. If I take my other 2 case fans and make them pull air inside the case then having this as another exhaust would probably assist the total cooling of the system as well.

    I loved this review, and thank you corsair for creating this product. People with existing water cooling can free up their loops for their video cards now / etc

    I'm beginning to look into this Corsair system the H70 specifically...

    My question, and I can't seem to find a definitive answer on Corsairs page or in this thread or in reviews but...

    How does the water never need replacing? Normal W/C setups require a reservoir top-off but this doesn't. How is that?

    Is it not regular H2O? is it some kind of coolant mix?

    What's long term durability of the H70?


    My goal is to O/C to about 4-4.2ghz on my 1090T and on air w/ my current Arctic Cooling Freezer 7 Pro, it's just not feasible temp wise.

    Well, according to Corsairs Faq:

    Q.Will I need to fill the unit with water? Do I have to perform any maintenance?
    A.Both H50 and H70 units are designed to be a closed-loop solution with no maintenance required at all. The units come pre-filled and feature proprietary hoses that virtually eliminate evaporation of water. The expected lifespan of the average unit is significantly longer than the 2 year warranty period.

    Q.WhatÂ’s the liquid inside the H50/H70?
    A.The liquid inside the H50 and H70 is distilled water with Propylene Glycol added to prevent corrosion and organic build-up.
