Hi I am looking for a new CPU cooler for an i7 950 OC 4Ghz I have read a ton of reviews about the H50/H70 a friend of mine got the H50 and said it was a very good cooler, looking at the reviews for the newer H70 it does not look like there is a massive improvement in temps etc over the H50 if you added to noctua fans push pull set-up you would have a quite cooler with low temps for about the same cost as the H70?

I have also read some reviews on the A50 and A70 which seem to do a good job or the Scythe Orochi Heatsink which is a beast but runs very quite

any other suggestions

thanks

Not much of a performance difference between H50 and H70............. and they are no better than some top air coolers............ and the radiators can be louder than air coolers............

If you are not bent upon these corsairs my suggestion would be the below air coolers

1. Thermalright Silver Arrow
2. Noctua NH-D14
3. Thermalright Venomous X RT

For the third one go for two PWM fans in a Y splitter in push pull config....... My recommendation would be Sharkoon Silent Eagle 120MM (for around $18). The Y splitter would be something like this http://www.newegg.com/Product/Product.aspx?Item=N82E168...

This is one of the de-facto lists that most people reference when talking about quality air coolers. The H50/H70 do about as well as any of these...but cost 2-3x more...and are fairly loud (if using high CFM fans to get similar results). H50/H70's are just P.O.S. as far as I am concerned; they typically leak, have poor flow rates and perform very poorly for the cost.

And for a totally different opinion
The H50/H70 when properly set up perform as well as or slightly better than most aircoolers.
They don't "typically" leak but there have been some reports of it happening,I have 3 of them running and haven't seeen a leak except for out of the 1 that I have modified several times.

They are more expensive than high end air, but if caught on sale the H50 and a spare fan are around the same cost as a Megahalems and fan.

For a similar price to the H70, there is a better starter kit, the XSPC Rasa kit or even piecing together some budget components...most watercoolers would suggest this over the H50/H70's.

The Swiftech Apex kit is an even better starter loop:

Great. If you get through all those you are doing good. Let us know if you have any questions...it's the people that refuse to learn anything and continually ask questions (typically answered over and over by those stickies) that we really dislike engaging with. We like informed consumers and people willing to learn on their own...those people are much easier to help.

I just wanted to point out that for the cost of H70's, there are other alternatives for 'watercooling'. I just like to inform of all options and provide as much info as I can...hopefully each person can figure out what is best for them and make an informed decision.

i haven't seen that great of reviews for the H70s IMO its the same thing as an H50 just add another fan and it looks like you would get the same efficiency as an H70.....not completely the same but closer to it since the H70 has a push pull configuration.

H70 supposedly has a bigger radiator, and 2nd fan. Outside of that, I really fail to see the improvements. The pump is still a piece of junk from the few tests I've seen on flow rates. Even Corsair fails to put the pump specs on their site.

They try hard to justify it as a good cooler (It performs on par or slightly better than top end air coolers!), but they fail to compare price + performance.

There are other low-cost, good performance air coolers that will fit in cases without much room (which is typically the argument for the H50/H70).

i guess you could say that its for the noobish poweruser who wants liquid cooling but is afraid to go all out and do a bunch of reading on a system and potentially mess something up lol

i would buy the A50 and just add another fan and you should be set if you have a high flowing case and a good thermal compound.


what price range are you looking at to spend on a cooler??
November 19, 2010 7:34:43 PM

Hi I went witht he A50 I used CF2 paste and swapped the standard fan with a 120mm Enermax UCMA12 Magma TWISTER Fan its the quietist fan I have at the moment my idle temps are 42 - 44 if i run prim it maxes at about 70 -72 after 10 minutes does this seem a little high?

70*C and under at full load is perfect....72* you r pushing it but thats still ok. but just 10minutes???

dude leave prime ruining for a few HOURS to get accurate results :D 
November 19, 2010 8:06:10 PM

I just added the corsair fan that came with the cooler to the other side of the cooler in a push pull config and the temps are idle 44c ?? wtf I haven't overclocked it yet its still at stock 3.068 I have a corsair 700D case with extra fan on the base sucking air in, on fan on rear sucking air in, next is first cooler fan then cooler then new fan

Air flow ------>fan -case-- --fan-cooler-fan --->

and I have two fans on top pushing air out

do these seem high temps for stock ?

you want the fan that moves more air pulling out the back of the cooler I believe, if the one in the front moves more air then some of the hot air doesn't circulate.
November 19, 2010 8:16:19 PM

ok this is wierd if I remove the lower case fan and the second fan from the cpu cooler and turn of one of the top fans I still get 43C ? surley more fans = more air = cooler cpu?

a b K Overclocking
November 19, 2010 8:20:51 PM

not always.....poor fan circulation can make it worse if you have an air flow short circuit
November 19, 2010 8:45:35 PM

maybe you have to much intake which isnt letting the hot air escape, more exhaust fans?
November 19, 2010 10:11:25 PM

Core temp shows my CPU as 47c and speedfan shows it as 34c ? under load prime 5 min core temp 69c and speedfan 60c ? which should I consider acurate?? what is a good idle temp for an i7 950 on air has anyone else used or use a corsair A50?

thanks

Yes with Prime 95 running withought prime just normal system load 43 -44c at 3.07 stock speed is this not good? I am looking at getting a noctua fan soon as the noise to airflow ratio is very good.
November 20, 2010 7:43:31 AM

update I have removed the rear 14mm fan, I have added the original corsair fan pulling air through the cooler to the rear case vent, I have an eranmax fan sucking air into the cooler O.C 4G

see images temps 44 - 46


it goes to 100c with prime 95 see image

OK mike... for clarity let me say this again on airflow inside cases... air intake from outside has to be from the front and/or bottom and air exhaust to the outside has to be from the rear and/or top...

The case originally has 3X140mm fans (one at rear, one at the bottom and one at the HDD drive cage) and optional 4X120mm fans (three at the top and one at the bottom)... From what you have said you have have the fan setup like this...
"I just added the corsair fan that came with the cooler to the other side of the cooler in a push pull config" - two fans on your corsair A50 in push pull config (OK)...
"extra fan on the base sucking air in" - one 120mm optional fan at the bottom for intake (OK)...
"one fan on rear sucking air in" - the 140mm fan at the rear acting as an intake (totally wrong)...
"next is first cooler fan then cooler then new fan" - you have the push pull config of your A50 facing towards the front of your case (totally wrong)...
"and I have two fans on top pushing air out " - two optional 120mm fans at the top for exhaust (OK)

Just to give you an idea i have drawn the air circulation on a 700D case for your info... http://img163.imageshack.us/img163/181/corsairobsidian7...

You should have the following fan and cpu cooler setup done for your case...

AIR INTAKE
1X120mm fan at the bottom
1X140mm fan at the bottom (between the two compartments "original config")
1X140mm fan at the HDD cage (original config)

EXHAUST
1X140mm fan at the rear (original config)
3X120mm fans at the top

The CPU cooler airflow direction should be from the front of the case towards the rear or from the bottom of the case towards the top... the psu will take care of its own airflow...

EDIT - my post was before you posted the pic
November 20, 2010 10:10:02 AM

thanks for the responce to clarify my current setup

if you look at the picture above I have no rear fan on the cooler I have the fans facing towards the rear vent pushing from the front of the case, the 140mm fan from the rear has been put on the bottom of the case

I have 2 120mm fans on the top of the case as exaust see image bellow

your temps are high... try doing this... change the direction of the cpu cooler so that the airflow is from bottom to top (blowing towards the top exhausts)... i reckon this will ease things a bit...

whats the temp at load??? Idle temps seems to be purrrfect...

Go for thermalright silver arrow (i have a noctua) since they are of the same cost and silver arrow performs better overall... with this your temps should be like
No OC idle= 35 load= <60
4G OC idle= 45 load= <75

I never got to know your ambient temps... these are for around 25 ambient...
