I'm working on a Jasper JTAG project and I'll replace the GPU HS for a 2nd generation CPU HS, make a shroud...etc.
But I'm also wandering if a Hybrid Extreme kit may help getting temps down, and hopefully extend the lifetime of my Jasper?

I know some people will say nay just because you shouldn't "fix" something that isn't broke, but I'll ask those people, Why not?

So far I've used 2 of these kits (Mind you, I also did a reflow using a heatgun and "No Clean Flux" ...waiting for a rework station), and both are still going strong for 3+ months.

jaspers require no heat mods.  doing one is really just asking for trouble.  i can't stress enough how pointless anything is other than cleaning the dust out as often as you update the dash and changing the thermal paste when you jtag just cuz i find it easier to wire them with the sinks off.

Theres not really much point considering that its a Jasper and they never rrod whats wrong with the x clamps anyway?

[xboxhaxorz]

so much wrong information. people think jaspers are the the holy grail, there is not many RROD because they are the newest revision. give it some time and they will start to show up more. i have had 2 that RROD from customers.

if you want it to last, do the water cooling

Personally I would just wack a 120mm fan on top of the xbox because one it keeps the temps down and two it looks cool!

PLUS: You have a jasper - not a lot or RROD on them plus if you install the cpu heat-sink on the gpu then definitely shouldn't get and rrod errors that are to do with the chips. The hybrid extreme kit seems like a good design actually. I would go for it not forgetting to place arctic silver 5 as your paste or else you can have 50000mm fans but wont make a difference coz of your cpu paste.

Actually I will be using different (bigger) fans.
I will also replace the thermal paste with something better (I'm pretty sure I'm out of AS5, but I have some Shin-Etsu G751 coming my way, if it doesn't come in time I have several others that will do the job just fine).
And yes the Hybrid Extreme Kit does seem to be a good design, the reason why I picked this kit in the first place (after doing a lot of searching) is that they seem to have done a lot of research.

Why is it that people can "fix" RRoD's using X-Clamp "fixes" (Albeit temporarily)?
It must do some good then, not?

The X-Clamps exert all pressure in the middle of the CPU/GPU causing the board to warp slightly, the Hybrid Extreme Kit has 2 pads that exert pressure more evenly, and they also make the chassis act as a passive heat sink (Supposedly it could drop temperatures by up to 6C).
I fixed my Falcon (one of the crappy Falcons as it didn't last very long) and I could feel the bottom of the chassis getting pretty warm, meaning the pads do work.

Yeah I thought about water cooling, but for now I'm broke

All I want to do is to keep it running as cool as possible, at a minimum cost and with as little noise as possible.
You'll just have to wait and see what I have in mind

And I know that if I want it to last I should do a proper re-flow (preferably re-ball the CPU/GPU/HANA/RAM and SB using leaded solder), but I may do that once it breaks down (Already ordered a rework station and considering to order some re-ball stencils).
I'm also aware that I may kill it because I need to figure out the temperatures and time, but I have two 360's to practice, and I'll start at a temperature/time that is most likely too low/short and then go up from there.

Comments are still welcome, but please try to explain why it is a good or bad idea, I know you shouldn't fix anything that isn't broke, but some modifications may also prevent something from breaking, right?

if screws and washers did good, then they wouldn't perma break consoles.  its easy to believe they work cuz people are quick to brag about fixing a console for $6, but when their console breaks a few days later they are always to embarrassed to come back and admit they were wrong.

Screws and washers don't break consoles, they temporarily fix them, meaning there must be a flaw in the design, please tell me what the flaw is in my thinking?
How can something break, which you can "fix" (Albeit temporarily) by screws and washers? It must be the flawed design (Maybe that's what I'm willing to think), but I really don't have a better answer to that.

For sure something is off, if it can be "fixed" using screws and washers.
Mind you, the Hybrid Extreme Kit is nothing like just some screws and washers.

Did you even take a look at the Hybrid Extreme Kit, order one and use one? It's no $6 fix, it's a ~$17 "fix".

Oh and I for sure won't be too embarrassed to admit I was wrong, I'm here to learn and help others, and I'm willing to share my experiences (good and/or bad), but so far the Hybrid Extreme Kit seems very promising (Still have 2 left).

But as I expected, mostly nays and no constructive feedback.
I'll use one just for fun, by the time my JTAG Jasper breaks I'll let you know.

It's bad enough people are using these bolt pressure tricks to "fix" broken BGA contacts but applying this garbage to a perfectly good Jasper is an absolute sin.

YOU WILL NEVER EVER EVER GET EVEN PRESSURE WITH BOLTS! NEVER! What are you going to use a micro torque wrench? How many foot pounds is safe for a GPU substrate? You're going to FORCE it to stop heat expansion?

Tricks = trash.

Heat expansion is what breaks GPU BGA. The cooler you run it the longer it lasts. With Falcons and Jaspers you don't need to even mod the fans, just a simple shroud mod will lower your GPU from ~65C to ~45C.


Just something like this, just a few minutes with some duct tape, plastic or cardboard:







These shroud mods simply force more air through the GPU Heatsinks where it is needed most.


Of course if you can do without a DVD drive, something like this is ideal:
