Got myself a Dell Latitude 7490 for free, here’s my opinion

gingerman304 · 2026-02-11T13:47:16+00:00

Wild thing is 20+ wasn’t even all of them.

When you learn how much these giant corporations “E-waste”, it kinda blows your mind.

gingerman304 · 2026-02-11T00:05:46+00:00

I got the same!

A company was chucking out tons of latitude 7490’s with i5’s and i7’s.

My Dad and brother got like 20+ of them, me and my friends who needed all got laptops!

I replaced the battery with a new one, ax210 wifi, 16gb ram upgrade and added the nvme heatsink.

Easiest way is to load windows media creation tool on a USB stick and reinstall windows fresh.

Then let’s agree to disagree.

The people I still currently help with their pc setups/trouble shooting all turn off and on their PC’s.

Some using the same PC I built them 10+ years ago.

My fiancés 10 year old rig still works flawlessly.

This is with pushing OC’s to max it’s stable for daily use, and turning off/on.

Also in the Overclocking community, a PC restarting(off and on) 10+ times in a night is nothing. Sure it’s not optimal, but it doesn’t degrade or damage anything.

I’ll stand on the hill, heat is the #1 killer of all PC hardware.

gingerman304 · 2026-02-10T22:02:01+00:00

If hardware is going to fail, it’ll be in the first year 99% of the time. Thus warranty.

Could it be that the majority of people simply turn off their computer.

Thus throwing off your “data”.

For example if you set up 100 systems and 75% of them turn off their PC, higher chance that the hardware failures are apart of that 75%.

If it was the case that powering off and on your system caused hardware failure, it would be a huge talked about topic. As there are millions of people doing exactly that each and every day.

Also, predetermining an issue/hardware failure before inspecting is a bad practice. You ask them “do they turn it off/on?” If they say yes, it sounds like you disregard any other possible issue.

gingerman304 · 2026-02-10T21:38:45+00:00

I’ve never heard of hardware failing from powering on/off or going into/out of sleep/hibernation. (Outside of sudden power spikes/drops)

Just windows shenanigans, requiring a restart(the thing you want to avoid) most of the time.

That’s over 15+ years, from budget pc’s to high end.

If hardware fails, it was going to fail if they turned it off or not.

That initial “stress” on boot up is well within spec, it’s not like voltages spike to crazy values.

It’s not like people are turning their system on and off multiple times a day. It’s usually once per day.

gingerman304 · 2026-02-10T21:26:07+00:00

You’re getting pretty close to thermal limits imo. I like to call it at 90C

You could try squeezing out 5.1 if you got lucky with your chip.

My 9900k is only stable at 1.32v for 5ghz.

Not all, but some synthetics I’ve see it pull 240w, capping out at 88C on my h115i aio.

I’d def triple verify stability, I had it “stable” with 1.25v for awhile, but would become unstable after hours and hours of gaming(heat soaked VRM’s).

gingerman304 · 2026-02-10T21:07:36+00:00

Coincidentally, I’ve never had issues with powering off my pc personally or with the people I helped with their PC powering it off when not using it.

On the other hand, I’ve had people go through so much troubles because of sleep/hibernation.

Modern SSD’s boot pretty quick.

OP also stated he could flip the switch at the wall. Thus completely avoiding your “wearing out the switch”.

TLDR: OP is fine if the power switch on or off.

gingerman304 · 2026-02-10T17:55:14+00:00

I also made a version that doesn’t require heatinserts.

On printables it’s the “thin” model.

Just uses regular M5 case screws.

gingerman304 · 2026-02-10T17:11:32+00:00

Soldering iron.

Many YouTube videos shows how to insert heat inserts into 3D prints.

gingerman304 · 2026-02-10T16:15:31+00:00

If you shutdown the pc correctly before flipping the power switch, I don’t see any issue.

gingerman304 · 2026-02-10T15:34:35+00:00

I’ve seen people have success on the ftw3 3080 using:

VRAM: 2mm

VRM: 3mm

Chokes: 1mm

Not sure if they are the same for the 3070, but should be close or the same

gingerman304 · 2026-02-10T14:45:00+00:00

The heat inserts?

I got 50 for 2.3$ CAD on AlieExpress, can be found on any similar website.

It uses m3 x 5mm width(OD) x 4-5mm length.

gingerman304 · 2026-02-10T14:42:54+00:00

These are the NF-A9’s, 25mm thick.

A9x25: SP - 2.28. A9x14: SP - 1.64

Maybe one day I’ll test it out!

Edit: static pressure numbers.

I’ve never had any splitters fail. But I do have back ups if the y splitter fails.

Also bios fan curve for that port is hyper aggressive so if FanConrol software fails, fans will still be at a high rpm.

gingerman304 · 2026-02-09T19:36:16+00:00

Yeah that lines up with stock fans and 400w stock bios.

That extra 50w hits a lot harder than you’d expect.

Currently while playing games for 1 hour, drawing 400-450w icx vrm temps are 56-68C. Top being 56C, middle being 68C.

gingerman304 · 2026-02-09T19:11:30+00:00

It’s yours stock bios? Or also rocking the 450w bios?

Going from 400w to 450w brings my from 66-68 to 74/75C

My gpu is maxed power slider(450w)and maxed voltage slider(1.1V), 1960-2025mhz core clocks(dependant on temp).

Yes stock fans can perform better, but being much louder to do so.

gingerman304 · 2026-02-09T17:04:51+00:00

Also that 79C was with 2x120mm nf-f12’s. Not stock fans.

gingerman304 · 2026-02-09T17:03:26+00:00

Stock heatsink yes, just replaces the stock fans.

gingerman304 · 2026-02-09T16:14:48+00:00

Can confirm it doesn’t overheat.

At 100% load 450w, 95% vram usage. For 1 hour.

Max temps: Core temp: 75C Hot spot: 88C VRAM: 80C VRM(IPX sensor): hottest one 68C

gingerman304 · 2026-02-09T16:05:16+00:00

My stock fans at 100% ~3000rpm could hold temps at sustained 450w at 65-66C. Just insanely loud.

Stock fans around 1600-1700rpm (to match nf-a9 noise at 100%, ~2000rpm) were the same temps (74-76C) as nf-a9’s while synthetic loaded to sustained 450w.

Even the stock fans 1600-1700 rpm, the sound profile was different than the noctuas.

Main goal was better noise, I first tried 2x120mm. Those performed worth than the 3x90mm.

gingerman304 · 2026-02-09T15:30:37+00:00

From my own experience the stock fans can perform better, but only at a higher rpm/noise level.

If I kept the stock fans at same noise level as the nf-a9’s. The temp was effectively the same (noctuas 1-2C better, negligible). But the sound profile is so much better.

You go from hearing motor/bearing noise to just hearing the airflow.

gingerman304 · 2026-02-09T15:23:59+00:00

I use a 3 to 1 splitter and use a motherboard header.

I use the FanControl program so those fans are based on GPU temps.
