Hi everyone, first time posting here Anyway long story short...as you all know summer is here, and I think most of us have experienced our PC running hotter than usual. While my own PC is still couping fairly well, my dad's PC temperature seems to be affected more than mine. My dad's PC has a E5200 oc to 3.8GHz with a Arctic Freezer Cooling Pro 7 as the CPU cooler. Tried disabling the smartfan in bios and let the Arctic Freezer Cooling Pro 7 running at full speed (gone up from around 1000rpm to 2800rpm) seems to have little impact on lowering the CPU temp with it idle at 54C. I've checked the rear case fan by putting my hand near the rear of the case, and although it is spinning at around 2200rpm, it doesn't seem to be shifting the hot air our of the case too well. So I'm now considering replacing his 120mm rear fan. I have looked at the Scythe Kaze Jyuni 1900RPM 120mm fan, and it seems to shift air quite well according to the users. Anyone else got any suggestion on alternative that I should consider? Thanks.
Firstly make sure your CPU cooler is working correctly. Try reseating it with good quality TIM such as Arctic Silver 5 (don't use too much). If that doesn't improve things then this article first http://www.bit-tech.net/hardware/cooling/2009/09/28/what-s-the-best-case-fan/1 then check this comparison table out http://www.quietpc.com/gb-en-gbp/products/120mmfans. Do you have the option of an intake fan (e.g. at the front of the case)? There are three fans I would recommend, although I tend to lean to quiet fans...what case are you running?

I'd look at these fans: they're both fantastic coolers and offer next to no noise. http://www.cclonline.com/product-in...egory_id=736&manufacturer_id=0&tid=nf-s12buln http://www.cclonline.com/product-in...egory_id=736&manufacturer_id=0&tid=nf-s12bflx
Next to no noise and absolutely no pressure/airflow whatsoever. Do NOT grab these if you already have problems with not having enough airflow With the current motherboards and their good fan controllers I just feel like choosing a fan is very straight forward. Just get one that has high enough performance and tune it down if the noise is too much.
Noctua NF-P12 UK price (at time of review): £17.99 (inc VAT) US price (at time of review): $22.29 (ex tax) Although the Noctua NF-P12 spins at just 1,300rpm, its nine-blade design is supposed to produce lots of static pressure at this low rotational speed. The NF-P12’s speed can be adjusted by two resistor cables that slow it down to 1,100rpm or 900rpm. At 900rpm, the NF-P12 failed to inflate the black sack, so its cfm would appear to be 6cfm or less. At 1,100rpm, it produced 18cfm and emitted 27.2dBA. At full speed, it shifted 34cfm but was a rather noisy 32.8dBA. As such, despite including vibration-absorbing rubber pins, the NF-P12 isn’t really ideal at any of its three speed settings. Noctua NF-S12B FLX UK price (at time of review): £17.99 (inc VAT) US price (at time of review): $25.99 (ex tax) The NF-S12B FLX is optimised for moving air at very low rotational speeds, which helps to explain why Noctua bundles two resistor cables that can set its speed to 600rpm, 900rpm or 1,200rpm. At the two lower speed settings, the NF-S12B FLX was extremely quiet, but failed to inflate the black sack, which indicates a sub-6cfm airflow and very low static pressure. At 1,200rpm, the NF-S12B FLX produced 28cfm but was a quite noisy 36.6dBA. Due to the NF-S12B FLX’s poor results at all three speed settings, we can’t recommend it.

Thanks for the info. Anyway, my dad's PC is used as a HTPC, and is placed about 9 feets away from the sofa, so I think for choosing the fan it would probably be airflow>silent (as I doubt the fan is audiable over his HI-FI system anyway). The intake and exhaust fans in his case is probably some cheap generic fans, so I'm guessing now is a good opportunites to swap them out for something better. Looking at the comparison table of quietpc, I guess the Scythe Slip Stream 1900 (Scythe Kaze Jyuni 1900RPM) would best choice considering it move the most air, and slightly highernoise level is not gonna be a issue for my dad's usage. As for the Arctic Cooler Freezer 7 Pro heatsink I believe it should be seated properly, but I think I will replace the MX-1 paste that pre-applied on the heatsink with the MX-3 that I got when I install the fan(s) for him. Thanks for the advice again.
The Noctuas suck, don't get them. I have 3 of them and they offer nothing for static pressure. At low RPMs the air is still moving slow through my radiator. At high RPM it is really loud. I got a gentle typhoon which is much much quieter at high RPM. At higher speeds the airflow is a lot higher despite no exaggerated claims of higher pressure.
The Slipstream 1900s are LOUD. I originally had 4 of them on a rad. My wife thought I'd changed the habits of a lifetime and was actually vacuuming (as if).
Sharkoon silent eagles are definately very quiet, sure they move lots of air but my mobo cant control them so having to wait till Zalman fanmates are delivered to up their speed.
I use the Sharkoon Silent Eagle 1000's and they do seem to shift a decent amount of air considering their rpm speed and noise level. Even in the 28 degree temps we had on the weekend, my overclocked i5 was still idling at around 45 degrees.
