CPU Clock Rate

3.6 GHz

CPU Temperature While Idle

35.0° C

CPU Temperature Under Load

70.0° C

Description

A 0dB configuration designed for every-day office work that supports up to 3 monitors.

I have tested it for two weeks with the 200mm case fan disconnected and an environment temperature around 21°C (NO FAN, 0dB noise). At those conditions, CPU's temperature is between 35°C (idle) and 70°C (full load). (temperatures recorded with RealTemp 3.70)

[No data for higher environment temps yet].

[WARNING]: The only shortcoming of CPU cooler CR80-EH is that it allows ONLY ONE memory stick with regular profile. Possibly, a low profile memory would fit but I haven't made a try. So, why choosing such a cooler when more space efficient form factors are available? The mobo in the Thermattake V1 is mounted horizontally and Coolers like CR80-EH or CR-95C work better in this conditions because they don't have a (strongly) preferred flawing direction for warm air. This favorites natural air convection with no active fan (I don't have a single active fan).

The hum of the fanless Seasonic 400 is barely audible and this is a huge pro to me.

The new 8th gen i3 makes the PC very responsive with its 4 cores (even if compared with my previous i5-7500). I consider i3-8100 one of the best choices for a mid-low budget PC.

In conclusion, this configuration satisfies the needs of a decent every-days duties PC without producing any audible noise.

Part Reviews

CPU

A great value CPU. Good performance for a cheap price. I use it in my office PC and it works great.

The integrated graphics allows up to 3 monitors. This is a huge pro to me

CPU Cooler

PROS: A good CPU cooler with a proper form factor for horizontal mounting. It can handle a i3-8100 TDP without the help of case fans.

CONS: It's huge and it might create problem with ram sticks. In my case, I could mount only a single memory stick.

In comparison with other coolers such has Cooler master H110, its more difficult to mount.

Motherboard

A very feature rich mobo including wifi and bluetooth.

The new Z370 is mandatory for 8th gen Intel CPUs

Case

I love its form factor: a small white cube <3

Power Supply

A fanless PSU with platinum certification at a reasonable price.

PSUs circuits normally produces a hum. In the case of Seasonic 400, hum is barely audible and this is a huge pro for a funless device, which is supposed to be quite!

Awesome build!

That feeling when over half the inside of your case is the CPU cooler. :O

It really is an awesome build for its intended use. I'm surprised OEMS don't try using NoFan coolers with their office PCs they sell.

The best part about it all is that you can play basketball with paperballs, while the computer is even running, since there's no fans to catch them on. :)

The cooler is so big that I couldn't install a second RAM stick. So, pay attention if you intend to use this cooler with a Mini-ITX mobo.

I gotta try this! XD

I use low profile DIMMs and they fit fine into both slots on the AsRock Z270 Fatal1ty ITX/AC motherboard I built with this case last February.

This is really cool. I didn't know fanless PSUs were a thing before this build. The more you know.

I have fanless PSU =)

Brendon_Carr 1 point 16 months ago

NoFan has a 400W power supply and it has no hum at all. Absolutely silent.

Very smart build.

vinhom 1 Build 1 point 16 months ago

Can you fit a GPU on the PCI-E slot?

Brendon_Carr 3 points 16 months ago

Yes. I've got an NVidia GTX 1060 in there.

vinhom 1 Build 1 point 16 months ago

Thanks, this build has been very helpful to me, I can see myself doing a similar build soon. Also, you seen to have swapped the left and right side panels on the case.

Brendon_Carr 1 point 15 months ago

Well, the pictured computer is actually not mine (I'm not the original poster, but rather a random commenter) — but yes, with this case you can swap the three panels (top and sides) at your discretion.

vinhom 1 Build 1 point 15 months ago

Well... that was awkward.

Does your PC use the same motherboard and CPU cooler combo?

Go get a Palix gtx1050ti passive cooled

bferra submitter 1 Build 1 point 15 months ago

I excluded it just for budget reasons but i think it a great passive cooled solution

DopeAF123 1 point 15 months ago

were did you get the cooler?

woahwoahwilly 2 Builds 1 point 6 months ago

Does the motherboard not have an M.2 slot? If it does, why not a much cheaper 500GB WD Blue M.2 SSD?

Just saying. Would've helped on cable management and still been cheap.

bferra submitter 1 Build 1 point 2 months ago

Sorry for this super late reply.

Yes, the modo has m.2 slot

You are right. For most cases this configuration is a 'bit' oversized.

I use several VM for my job, so having decent CPU and RAM amount is important to me
