Didn't they have a matching black crate?

I'm not sure whether this goes in Ghetto Mods, but I'll post it anyway.

I had old and perfectly working Intel Core 2 Duo E7400 CPU which was susceptible to Spectre and Meltdown attacks.
So I upgraded E7400 with new security feature which makes it keychain-compatible v2.0. It's also makes it permanently resistant to Spectre and Meltdown attacks.
Don't worry, you aren't lost. You can also make your Core i7's, i9's, Ryzen 7's and Ryzen Threadripper's compatible with keychain v3.5, which is far more advanced.

On the other hand, I'm waiting for a working Intel Xeon W3530 in mint condition to make it keychain-compatible v2.7. This one will be for me.

I will give this E7400 keychain as a gift to my younger cousin. The hole was drilled with 2 mm drill bit. It took me 10-15 seconds to carefully drill trough PCB.

Does it suffer the post Spectre and Meltdown Fix Slowdown............?

 

[Komshija]

@dorsetknob Depends how you drill the CPU. If you drill it trough the IHS, it does. If not, than you can actually expect a 8,26% boost.

I still need to sand these edges, although they aren't that sharp. It will make it more aerodynamic for better airflow and thus better cooling.

 

[Papahyooie]

I have seen a few people do that, and run a small USB battery pack to some specific pins and make a portable hand warmer.

my nephews 750ti began acting poorly, i ended up finding it had bad fans, so i decided i would try a "modification", as MSI refuses to sell me a replacement shroud, and these GPU's have fans permanently affixed to the Shroud, this was my Ghetto fix

found a replacement fan on Ebay for $6 (shipped)

i removed the fan housing, and ended up with just a fan & a wire. fitted to the 750ti shroud, it seems to make a very effective, and aesthetically pleasing resolution IMO, now i just need to order the other fan,

That VRM gets wayyy too warm in warm days here in Portugal, so i fixed it!

They blow some minimal air right on top of the back core and portion of the VRM. There are pretty big holes in the backplate which makes airflow possible. Temps dropped with 7 degrees with fans on 40%.

Frankly, the Brand Computernerd in the USA was known for selling modified Slot A Athlons, and seems to be out of business these days. Not much to be found about it.

my current case has a problem, the 5.25 inch covers are kinda loose
so i drill it and using UTP cable to secure it

"Wot no Hot Glue Gun"

 

[jboydgolfer]

Ac66u was getting hotter than id like, so i cut a small square out of the casing under the heatsink, & hot glued a 50mm fan to blow inward. I removed the original two pin connector, and instead spliced on the power wires from a USB connector, which plugs into the back of the router . Temps went from 116f to 102f.

Out of curiosity, what is your indoor temperature ? mine hovers ATM around 30-31ºC(86 F) without a/c.

 

[dorsetknob]

76F no AC

 

[jboydgolfer]

what is your indoor temperature

roughly 75F (but this router sits on my office desk among clutter, of modems, Monitors, PC's etc, with a light over it). I only have 2.4Ghz enabled, and iirc only up to Wireless-N. A couple years back, i cut some ventilation holes in he sides of the Routers casing, and have noticed some minor reduction in temps. But after adding this small fan, the change is significant. Admittedly, there are MANY devices in my home connected to this router, and it works very hard in the evening, the CPU usage is normally around 90%+ all the time with each of 5 people having 3 or more devices. It wasnt having issues from the heat buildup, and it has never shutdown or anything, i was just bored ,and figured WTF?

you can see in the perf monitor in the routers UI, it has dropped 15F, and will continue, how far is up to 20F, maybe a touch more, but around 20F all said n done,

*EDIT*
ending up stabilizing out at around a drop of 22F!! not bad for a $5, 50mm fan, huh?

Just reminded me i still need to get a fan for my Linksys SR2016, now that thing gets toasy, a good 40x40mm fans are frigging expensive.

that blue tape, why you need zip tie when you have used tape?

 

[Tomgang]

This month I have replaced every single fan in my old system accept for PSU. I also installed new fan controllers that have temperature sensor build in. One of the sensors I mounted on chipsæt heatsink and that's where I saw that chipsæt on my motherboard got fairly hot with the oc on CPU I run now + in my country its summer and freaking hot right now and a GTX 1080 TI also take its share of heat development in the case dosent help either. Something had to be done about it.

TIme to Ghetto mod the system with fans and zip ties.

Had to zip tie cpu cooler a bit to hold it up so it dit not touch the two fans on chipsæt else the fans made a terrorble noise.

Fans + zip ties + chipsæt heatsink + a lot of patience = 15-20 degrees celsius drop on chipsæt.

Also took the freedom to install two small fans next to GPU.

For those of interest, These are the fan controllers I installed. Called nzxt sentry 3.

This is why I ordered a new case today.

Damn, you have a faster keychain than I do! Mine is Pentium 4 Northwood 2.66GHz with pins soldered away

Some more ghetto from my office:
I've decided to move some trash around and found enough parts to build a super-cheap mini-server for my networking experiments(came out to be almost twice as powerful as my part-time bosses small edge router + mail server in his place).


First, I pulled out a semi-functioning AsRock J2900-ITX board from my trash pile, where it ended up last year cause both Asmedia controllers died (leaving only a pair of working SATA-II ports and half of available USB). As you can see, there's some residual flux near two empty placement pads on the board: had to remove both chips and cause it's a trash build - f@#k cleaning, no one'll see it from the inside anyway. USB ports are bugging-out sometimes, but all I need for now is for one of them to pick up my bootable stick and hold on 'till I have my distro running. Also, I some time last year I've attempted to remove two non-working SATA ports to prevent confusion, but gave up after the first one.

Second, I had to cut some fins from that stupidly large heatsink, cause my HDD mounting bracket wouldn't fit. I say stupid, cause ECS had similar boards with a heatsink half that size made out of plain aluminium and no fancy paintjobs, and it did much better job at cooling a 10W SoC.

Lastly, I've installed everything into a brand-spanking-new slim ITX chassis which I bought for $1.50, added a spare 320GB 2.5" HDD, which I got for free, topped it off with a single 4GB DDR3 stick (which was my BGA practice victim, put together from two non-working Elpida modules), installed Ubuntu Server and off we go!
I've also added an Intel wireless card(not shown) for some future upgrades. Just ordered a pair of RP-SMA to IPX pigtails for external antennas, so I can run it as a secondary access point at home. Just need to drill some holes on the side, and maybe put a silly sticker on the side panel.

That's surprising, because the merlin chart/software doesn't even have an entry for anything below 100°F or whatever it's equivalent is in Celsius. It does read if you look at the details but the chart is just blank ,because it's not high enough temperature to register ,because the chart begins at 100°F or something roughly around there .

that blue tape, why you need zip tie when you have used tape?

I dont recall , probably to keep the cables together ,or too shorten the cord ,because it was like 6 feet long and it only needs to be 10 inches

Just reminded me i still need to get a fan for my Linksys SR2016, now that thing gets toasy, a good 40x40mm fans are frigging expensive.

does it have to be 40x40? or can it be larger? i might have a larger size fan of decent quality kicking around, iirc, sub 80mm, but im not sure exactly

That is awesome... this was my first 100% custom build chip... the e7400 allendale...

 

[jboydgolfer]

that blue tape, why you need zip tie when you have used tape?

I remember now, the tape is covering where I spliced the wires together, and the zip tie is to shorten the cable because it's several feet long

 

[Ruru]

E7400 was Wolfdale-3M, not Allendale like C2D E4000 series (and Pentiums and Celerons which were those with lower L2 cache)

Ah that's right!

Okay so I'm building rigs for the roommate's kids and a few people from here (you know who you are ) helped out. Well one of the wifi cards wasn't really doing too well to the point of in games, the player can try to go forward but instead go to Pluto and back with a detour to some other galaxy. Anywho I decided to stick the card in a system that's much lighter on the network usage and for some reason the card works 300% better in this, uh, spot.

Antennas stuck to the back of the card. Gets 31/9 on speedtest which it was at 2/0.6 before. So weird stuff happens and it works better.
