Air Cooling in very Hot Climate - the Sandro way

Hi people,

This is a modification,... since I have no other choices and no other places,
to bring down the CPU temp by a supplementar air cooler, designed and installed
under the CPU socket,... I think like the last frontier,to avoid using of a liquid cooled system!
Sounds crazy also for me, but the results are there, and you can try and judge!
I've created this, for the case, when during a test of LinX I touched the metal cross
under the CPU socket and I felt it was hot, (about 60C°), while Core temp showed 73-75C°
medium temp on the cores.
I drilled two copper plates 100x50x5 mm. (total weigh about 1,0 pound) and I installed this
under the CPU socket over the metal cross(..see photo), using the four threaded holes
of the original socket 2011, and using a thermal pad 1.5mm between copper and cross.
Also I have installed in front a SCYTHE SLIP STREAM SLIM 120x120x12mm fan 2000 RPM
very silent, that pushes fresh air, drawn from a grid on the right side of the case.
I redid the same tests with LinX, under same conditions of room temperature and CPU load,
to obtain the following results with and without this supplement of air cooler:

------------------------------------------------------
Stress test @ 4500 offset+0,015 -room temp 28C° -Noctua NDH14 without copper plates:

LinX 10 steps ----idle -1 - 2 - 3 -4 -5 -6 -7 - 8 - 9 -10

CPU's hot core temp 28 66 68 72 71 70 73 72 75 74 76 (Core temp indication)

m.cross socket temp 26 43 46 49 52 54 55 57 58 59 61 (opt.3 sensor indication)

------------------------------------------------------

Stress test @ 4500 offset+0,015 -room temp 28C°-Noctua NDH14 with copper plates:

LinX 10 steps ---- idle -1 -2 -3 -4 -5 -6 -7 -8 -9 -10

CPU's Hot core temp 28 63 65 64 65 66 67 68 68 69 71 (Core temp indication)

m.cross socket temp 25 33 36 37 38 39 39 39 40 40 40 (opt.3 sensor indication)
-----------------------------------------------------

The temp. difference in the socket metal cross is about -20C°, which it is translate in about
-5C° medium on the CPU cores, and It seems to have a beneficial effect also on VRM temperature,
(shows from opt.1 sensor....37C°in place 39C°). Try before you criticize, five degree are not a lot but
..me too I didnt' believe it!

If you feel these tests unreliable and-or have a more accurate test, suggested to me how to do it.
If, however, you want to suggest me ...to buying a liquid cooler, I'm not offended, but...i dont buy it!
I'm not saying that this is the final solution for all the coolers, and if you need to assemble a new system,
rightly buy a liquid cooler ... but if you already have an air cooler of a certain level and cost like me
(es. my Noctua NHD14), then before giving up, try to help it in this way!

Ciao

Hi Snakeyes,


Thank you for your appreciation, I just thought that where there is heat there is dissipation, and therefore the dissipation must be helped, if you wont break down the temperature....!

Snakeyes hello, see you soon.

Hi Arne you are always the most humorous
Yeah, sure to be very careful not to touch anything with any tool and electrostatic discharge, what I think is the most sensitive spot of the computer.
When I installed the change I was worried that he could not work because of the plates that could increase the capacitive effects ... disregarded and disastrous @ 4 GHz and beyond ... but fortunately does not seem to have happened.
Also thanks to you for your appreciation of my work.
As to emigrate to Scotland has always been the dream of my wife!

Excellent work there sandro c.....I like that mod! and the results speak for themselves! of course anyone wanting to copy, make sure nothing touching the back of the motherboard or the back of the RAM slots etc....maybe point that out hehe

Only way to go lower is liquid...or move to Scotland 😉

Well done and very innovative.

Pretty cool mod, but if you dont want to go liquid cooling, why not just buy a closed loop one?

Thank you, HiWizMan,

I hope it can help those who have more money to spend on the CPU cooler, having already spent enough, however, glad that you liked it.
I have spent 10Euro for the fans, 5 euro for the termal pad and 3 Euros for the grid on the case .... the rest I did on my own ... the copper plates come from a control panel of a central electric demolished, cut, polished and drilled.
Happy also that is innovative ... will not ask royalties to those who will use it for personal use .... aha, aha!
Hello

Hi Myk SilentShadow,

the answer is simple and I already anticipated introducing the change .. because a few years ago, I already spent 75 Euro for the Noctua NHD14, 20 Euro for the fans more efficient and 5 euro for the 2011 socket adapter kit, total about 100 Euro.
Now is not a tragedy to spend 130 Euro for a closed loop cooler, but in these times of crisis it is a pity to throw away the Noctua which is always an honorable cooler, .... and then to live in the difficulties, trying every possible solution has been my credo for an entire life's work.

Wow, you really went the extra mile this time Sandro. Impressive. Yes, according to what I read Sukara said (or was it Raja?), the back side is also important to cooling the VRM. And yes, I can imagine it could also make a small difference in CPU temperature like you report, it only makes sense. I have to wonder though, does your report show the results with your case closed? Did you mod your case to allow airflow for this fan? Most cases will not have enough room to allow proper airflow in such a fan. And in my case, I would have to mod my motherboard tray area to get that fan installed, as my case does not have the proper opening for LGA 2011:

20420

Personally, I don't believe I would get more than 0.1GHz boost on my OC from this, so I wouldn't bother - just too much trouble for such a tiny boost. Even a 0.2GHz boost would be insignificant to me.


P.S.: I've been away from the forum playing Skyrim (W/Dragonborn DLC) lately - enjoying it too much. And my work picked up a couple months ago too, making my free time more valuable. When I do this I don't read the forum much, sorry.

But hey Sandro, kudos to you for your successful mod. We love to see stuff like this on the forum. GL to you.
