Good CPU cooler for i5 4690k under 140mm

xBACONxBUTTYx · Jan 12, 2015

I have the i5 4690k an wondered if there were any good coolers under 140mm. will probably look to overclock in a few years but at the moment, something better than the stock cooler. My case is Corsair spec 01 blue.

Thanks

noctua have a highly rated set of coolers to suit. Take a look at the Noctua NH-D14

He said under 140mm, that is 160mm. Noctua is a good brand though and I could recommend this: http://www.newegg.com/Product/Product.aspx?Item=N82E16835608025

Yeah was thinking of the L12, it's had some good reviews.

patrick47018 · Jan 12, 2015

Definitely a good choice, any other questions?

Nope that's all mate, thanks for your help

I'm waiting patiently to get my hands on the new Noctua NH-U9S.

125 mm tall. 95 mm x 95 mm footprint so it fits in place of a stock cooler.

The NH-D9L is an even shorter version (110 mm).

Both use the same 92 mm PWM fan. Excellent mounting system for both Intel and AMD. Looks to be the perfect upgrade to stock coolers. Plenty of margin at standard clock rates, enough reserve for mild overclocking. Recommended for installations up to 125 watts TDP.

What CPU are you using though?

hwc1954 · Jan 12, 2015

I use an AMD, but here is a comprehensive test of the NH-U9S on a test system with an i5 4670K chip:

At stock clock rates, under 100% CPU load, the CPU temp max'd out at 68C and the PWM fan was operating under 45% of its max (very quiet).

At heavy overclocking (4.6 Ghz), the cooler couldn't keep up. The fan ran at 100% and the CPU temp was thermal limited at 94C.

Backing off the overclocking (4.0Ghz), the cooler brough 100% load temps down by 15 degrees to a max of 79C.

So, I conclude that this cooler is a great choice for stock or mildly overclocked CPUs where space is tight in small cases. You can add a second fan and get another couple degrees of cooling. It's not going to perform like big 140mm coolers, but it's going to cool as well as or better than most coolers I've seen that will fit in the same space.

Here's a link to the whole review with a bunch of pics of the cooler installed.

So would you say the noctua NH-U9S or NH-L12?

Noctua says the L12 and the NH-U9S are similar in cooling -- 125 W TDP for AMD and 140 W TDP for Intel. The NH-U9S takes up a LOT less real estate on the motherboard, but it's much taller.

Been looking at the NH-C14 aswell for overclocking with i5 4690k, would you know what max overclock I could get and what temps, on the few we've talked about.

hwc1954 · Jan 12, 2015

The Noctua TDP list I posted has the NH-C14 as the same performance as the U12 120mm tower. Less performance than the U14 140mm tower coolers. The test review I linked above has the measured results for both of those on the heavily overclocked i5 4670. 84C for the U12S and 82C for the U12.

All of these are much more cooling capacity than the NH-U9S with 92mm fan. But, they are also much larger.
