Description

Needed a portable gaming pc. Wanted it to be brickless for my VM's and other related stuffs. i under volted to 1.25V, locked to 4.0Ghz on all cores, and its stable at around 29c idle - 55c load all the time. Super fast, even blows my 5Ghz all core 8086k out of the water.

yep my testing revealed- 4.1=60c-61c, 4.2=64c-65c, 4.3=69c-70c, 4.4=74c-75c, 4.5=79c-81c and i did not go further because i do not want my cpu to throttle or heat up my other components in my case.

Do you think for a non k version i9 9900, the cooler be enough to keep similar temps without undervolting / underclocking? I'm thinking of upgrading my pc (i7 6700k) never really overclocked so I have been thiking about going with non k cpu (to lower the tdp) and a h370m motherboard.

Well, yes if you look at noctua's site they list the 9900 as fully compatible 65w(heat may be an issue because you cant control the cpu). tho you cant underclock or undervolt a locked cpu if i remember correctly. thats why i went for the 9900k. mine is actually overclocked from base of 3.6GHZ to 4.0 locked on all cores, then undervolted to 1.25volts it maxes out at 69W. if you want to just save money get a K cpu thats lower end like the 9600k or 9700k there 6 and 8 core without Hyper threading. im actually very interested in getting my hands on a 9900KS to see how that would undervolt because of its superior silicone. if your just looking for maximum GHZ (speed) then dont waste your time and build something with space for watercooling. There is also a 35W model 9900T, but its clocks are really low.

I think you can probably push that 9900k a little further, like 4.3 ghz

Sure can actually went to 4.5 but with more heat than i prefer.

Astounding ! !

Where is the tiny 40mm fan sited and what function can it perform ?

Also - you've done more builds than Lego - What do you do with them all ? Do you sell them, pull them apart to make your new ones or what ? Just curious . . .

I think i posted the pics with the old black one it came with, i need to put more pics up sorry, the 40mm fan is on the power supply and run off the motherboard. As for the Lego comment, i build Lego models too lol. Most of my PC's are just sitting in my house unused. I've sold like 2, I'd like to sell more and do more builds but no ones really buying PC's anymore.

Hi

Kudos on your build.

Can you please post more pics and details about this build.

How you undervolted and underclocked, can you share screen shots of the bios? Which power connector did you use, c6?

thanks

Thanks for responding.

also, did you have to mod anything on the case?

ok, ill try to get them up, i had to Mod the graphics area slightly making a cut out for the DP and HDMI connectors. i had to drill a larger hole in front panel for the 19mm switch i used because i wasnt paying 30 for a switch i didnt even like and amazon had these for $4.55.
