Question: it says " Heatsink and Fan. " ... Does this mean a proper heatsink and fan such as a "Scythe Katana 4" is not needed?
Document: Not sure if I needed to do that but did anyway. On "AMD Stability test" temps only went to 50C at the 4.3ghz overclock. My A-70 Corsair CPU air cooler fans are set by BIOS to "CPU Auto Fan Control" and they do spool up and down as needed even though they are not PWM. (Mobo is adjusting voltage for speed contol)I'm buying stock in AMD!!!
I have 2 of these with the rog crosshair v boardsMake sure you get a good cpu cooler (h100 or a big dual 120/140 fan heatsink). I OC these to 4.4 (200x22) w/o voltage upgrades. If you plan on voltage upgrades to make it go faster - you need to get water cooling, as air will make you be at the edge of your seat watching the numbers
summer time 100 degree Fahrenheit without air condition) so this stock fan gets a little noisy, but still that is not the products fault.5/5 as it provides everything it says, and everything I expected.
I have removed the motherboard from the case and assembled on a non-conductive surface the bare essentials (MOBO, CPU, Heatsink Fan, 1 stick of RAM and 1 video card - installing them one at a time and powering on between component.) I attempted to troubleshoot with the guidance of a very helpful tech support forum and am still facing the same issue.
8-core. What more could a girl want? I bought this with myGIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard. Together, they make a great team. I didn't have to flash the bios or anything. They just work.The processor comes with its own heatsink and fan. Thermal compound is pre-applied in an even layer, so we don't have to worry about that ourselves.
Very happy with this, Last HTPC was intel I5 cpu 65 watts, Was kinda worried about the 125 watts needed to run this, but stock fan is almost silent, paired with ASUS 975 chipset motherboard ( when using FX CPU's use 9** chipset or greater ) 32 gig RAM, AMD Graphics card, LG Blu-Ray/ RW, in a nMedia HTPC case. Strong Increase in speed across the board, for about 1/2 the cost of Intel I7 upgrade........
Words cannot begin to describe my happiness with this processor. Fast, fast and yeah, FAST. Built my computer fresh from tower up and within very short time was playing games and downloading other games. I have yet to overclock this setup yet, as I have yet to watercool it. Infact if any complaint, it would be the tiny fan on the heatsink. Now, the heatsink, is very nice. It uses copper heatpipes that move the heat away well.
I have run games such as Skyrim, Dragon Age 2, GTA4, Assassins Creed 3, Sims 3, etc. at the highest settings with absolutely no problems. I was advised against this processor but i'm glad i chose it. On another note, the stock cpu fan is pretty lackluster but that is to be expected from a stock heatsink. Overall this is a great processor, maybe not so much for those hardcore gamers with monster rigs but it has done everything i hoped for and more.
Years ago I swore by AMD then eventually shifted to Intel as 'hyperthreading' took off. I needed a system for video editing and read tons of reviews for the i7 and this processor. A lot of favor was given to the i7, however careful research revealed that rather than focus on the processor alone, you have to look at proper system configuration even more so. I run industry standard software and process AVCHD files flawlessly with this CPU. The only real difference in my view with the i7 and the 8150 is cost.
Works great ! I have it over clocked at the moment to 4.7 ghz fan cooled friend has the same 1 that's at 5.1 water cooled worth it's price for sure
Answer: Well, It comes with a Heat sink and fan, but I wouldn't use it. Then again, I Over Clock. I never installed the stock Heat sink. I ordered a Corsair A-70. I run mine at 4.2GHZ and it goes to 44.8C under stress test. You reference the SK-4, that would also work well. But If your not going to OC, no need for after market HS.
