But the thing I'm quite puzzled is... based on the synthetic test of frostytech, the Xigmatek which cost 1/2 slightly edges over the Noctua

if u not going for heavy OC, just stick with the cheap one, the celcius different wont be huge

Was advised to get the Gemini Spire instead of the Xigmatek DK, but based on frostytech.com the DK seem to have better performance... but if look at the HSF design, the Spire Gemini has dual fan, 6 heat pipes! But somehow performance not as good as the DK?

unqeualtek, what kind of temp are you getting on your Spire? idle vs full load.

I OCed my 2500k to 4.2ghz at 1.24v, idle around 34c full load max around 75c

If I were to overclock i5 3570k to 4.5ghz for 24/7 with MSI Z77 board, suggest any good air cooler? Is Hyper 212 EVO more than enough?

hyper 212 evo + 2x arctic f12 pwm fan
good enough to OC to 4.5ghz

I see. Can you give me a link of the fans you mentioned? Can't I use the stock fan + one of the fans u mention? Or must it be 2?

use this fan can optimize better cooling than the stock fan

Hi guys, noob here ^^

may i know which direction the air should be blown for the fan in my case (not the cpu fan)? towards outside or into the case?

many thx

What case are u using? Normally front intake, side intake, top exhaust, rear exhaust

any low profile heatsink recommend ?

wta, any1 know where i can get silverstone AP-123 fan?
closest i found is by yongkeen but its AP-121.

Thank you for this information.
Is Corsair Carbide 400R case decent for good air cooling purpose?

Anyone using NH-L12 or use before? want to know how it performs.

does the direction(vertical or horizontal) of mounting tower heatsink affect performance?

i believe the air flow in ur casing only will affect the performance..

HORIZONTAL OR VERTICAL MOUNTING:
Reference 1>> http://www.overclock.net/t/727852/question...s-vertically/10
Reference 2>> http://www.overclock.net/t/1199135/hyper-2...cal-positioning

at first i thought about the effect of gravity on the liquid inside the heatpipes, but then both tests seems to point out that HORIZONTAL mounting being the better choice;
the result from Reference 2 also shows that removing the rear case fan would actually show better temp.

maybe i should do some tests and share the results after i installed my heatsink

Can the xigmatek nighthawk fit into thermaltake v3?

theoretically YES. Dark Knight heatsink is 159cm tall, TT-V3 maximum heatsink height is 160cm. my friend's V3 can fit Hyper 212 which is same height as Dark Knight.

Guys, any recommendations for air-cooler in a bitfenix prodigy with gigabyte h77n-wifi motherboard?

My CM Hyper 101 is sounding like a vacuum with my new I5-3570

Was wondering if its the intel TIM problem or the 3 year old Tuniq TX-3 i found laying around and used

Any recommendations for 80mm fan to replace the one on the heatsink?
