Kryonaut Extreme by Thermal grizzly gives excellent results. it is highly thermal conductive, non-electrical conductive, and while the industry was boasting 8.5-ish W/MK pastes as last gen thermal pastes, like the big achievement, Thermal Grizzly released a 12.1 W/MK and when the industry started boasting 9.2-ish W/MK thermal pastes as the big achievement of current gen, Thermal grizzly, released their Kryonaut extreme model, which is 14.2 W/MK. Compared to Arctic MX-5's 8.4 W/MK Thermal grizzly is on a new level, I saw difference 7 - 8 degrees lower temps, where: PSU is the same motherboard is the same motherboard BIOS is the same CPU fan rpm settings are the same case fan rpm settings are the same my CPU's are the same, CPU Heatsinks are the same CPU cooler fans are the same Case fans are the same, case is the same basically make the compare fair compare the thermal past only different thing, where everything else is the same.

My customer knows it is old. he told me clearly "i know it is old, but i want to use it until it works" so no worries about it.

currently the customer installed 3 of thee Noctua's Industrial PPC 3000 RPM 120 mm fans One as case intake, one as case exhaust, and one as push fan on the nh-u12dx-i4 heatsink following the general air flow. WS on in another floor and noise is not concern, access to the remote station is via remote access. But one still don't think two industrial fans can take anything more from this heatsink, compared monster and customer already has 33 deg. C idle temps on the package and about 53 deg C. for a 95 watt TDP CPU on the package when the processor is stressed with prime 95 for 90 minutes. note the 120 mm industrial is designed to be high static pressure, the 140mm industrial is designed to be high air flow, but working with those proves these can take any role high static as easy as high air flow.

I do not mean to be rude or disrespectful, but this is not my computer, it is my customer's computer. I am paid to make it work. if my customer pays i will take the money and make it work. Why he uses this platform? i don't know and i don't care. I am paid to make it work i make it work. By the way professional grade hardware do not age as bad as consumer grade hardware. but at the end of the line you are correct about one thing - it is 11 years old platform. if you ask for my personal opinion, i strongly agree with you - does it have potential -no. does it have future - no. My personal guess - the customer wants to use it while it works and when motherboard fails he will trash it

no, no overclock. i know it earth shattering statement, but no overclock.

Hello. The drama of my customer is a production workstation Lenovo Thinkstation S20. Server grade/production workstation grade hardware, overclock is neither usable or applicable option, though the cpu xeon x5660 is a good hint. The chipset is x58, based on IOH 5520 and ICH 10. The customer installed the nh-u12dx-i4 cooler. The heatsink has huge area, lots of fins, and it is not very deep. I believe the consumer grade fan is doing very well, and the second will be a slight overkill, one industrial will make all the pressure and airflow this heatsink can ever use, but 2 industrial fans on this heatsing it absolutely makes no sesnse on this heatsink

Baiscally of all i was reading so far you must have either a big-big single tower heatsink, two towers heatsink, or really inferior fans to justify all this trouble. Every half decent high static pressure fan is designed by original intent and design to push air with enough force (pressure) to move between the fins, trough the whole depth of the heatsink, as for syncing both fans keep in mind most fans are made with some percentage usually about 10% of different rpm as manufacturing tolerances, this can show its evil. Basically the faster rotating fan needs to ne pull fan to sustain the airflow. A good, high quality high-static pressure like noctua or others in the same category as noctua will push the air trough the whole heatsink with sufficient pressure to be effective. On top of that you will increase noise and get into more issues, to double the connections. If i was you, i was about to use 1 push high static pressure fan from Noctua's industrial line of fans. You will have relatively the same noise and power comsumption between 1 industrial and 2 consumer fans, but the airflow and the static pressure of one industrial fan will exceed the combined effort of both consmer fans for relatively the same noise. And as for the noise, big noise values are only when the fan is working at full power, but in pwm case, the fan self regulates to minimum useful rpm, negaring large part ot he noise. If a fan reaches full rpm, reducing rpm and noise. This also means your compiter is deep in the trouble, if a 3000 rpm fan is revving up to full power and your priorities will be other than a noisy fan, trying to save your pc from overheating. Keep in mind an industrial fan pushes more air - a bigger airflow with higher static pressure, compared to a pair of consumer fans, so you will have better cooling with one push fan, industrial grade fan at the same rpm, compared to 2 consumer fans basically forcing the fan to slow down and reducing the chance to rev up. If it rev up it will be less rpm that the pair of consumer fans.

This is why i say it makes no sense. My customer is not overclocking, and considering: 1 industrial fan alone creates the same airflow as 2 consumer fans exceeds the static pressure of 2 consumer fans.... X5660 is 95 Watts tdp CPU

Thermal compound is: Thermal Grizzly kryonaut extreme 14,2 W/m*K thermal conductivity https://www.thermal-grizzly.com/en/products/359-kryonaut-extreme-en Basically i also consider how much one fan alone pushes trough the heatsink 1 consumer version of the fan pushes about 93,4 m³/h in normal setup (No LNA) Min RPM 300 RPM (no LNA) Max RPM 1500 RPM (no LNA) Static pressure 2,61 mm H₂O (no LNA) 1 industrial version of the fan pushes about 186,7 m³/h in normal setup (No LNA) Min RPM - 750 RPM (no LNA) Max RPM - 3000 RPM (no LNA) Static pressure 7,63 mm H₂O (no LNA)

I start this topic not as requesr for help, but as general chat topic. A customer wants to beef up his cooling. He wants to put 2 nf-f12-industrialppc-3000-pwm fans in push-pull configurarion on the heatsink of nh-u12dx-i4 upgrading the stock fan. It makes no sense, it will not increase cooling capacity, compared to one fan, it will sound like roaring beast and being honest, one on these industrial monsters make far more air pressure and airflow that theis cooler can ever make good use of. Please share your thoughts on my customer's idea. Anyway i still, i believe it is good chat topic to fill idle time.

RAM is bottleneck for, 2 reasons: 1. 8 Gigabytes is not enough.... at least 16 gigabytes will do nicely, maybe 32 to be on the safe side and 2. Really? DDR2? These CPUs can run faster than this. Use DDR3 1333 MHZ to reduce bottleneck or DDR3 1600 to be on the safe side if chipset support it. I Really want to see these CPUs with 16 or 32 gigabytes of ram DDR3 1333 mhz or DDR3 1600 mhz to reduce bottleneck caused by ram

To the attention of Linus and Anthony: The way Linus presents things, on my PC, it does not matter if i am with intel core 2 quad q9650, 16 gigabytes, dual channel of DDR3 1066 mhz ram or if i am with intel core 2 quad q9650 ,16 gigabytes, dual channel of DDR3 1333 mhz ram, most likely i will not feel and notice improvement, because ram performance is only part of overall system performance and there are all the other aspects, that define overall system performance, but if i am with intel core 2 quad q9650, 8 gigabytes, dual channel of DDR2, 667 mhz ram and upgrade from to intel core 2 quad q9650, 8 gigabytes, dual channel of DDR3 1333 mhz ram i will feel notable system performance improvement. correct me if i'm wrong....
