Nice man. What happens it you put ice in the rad lol?
post #22 of 100
Excellent job thumb.gif

Don't worry about a modest range of temps from core to core, that is completely normal for a multicore processor, although TBH I don't have any first-hand experience with that particular chip. I'm sure if you did a little digging here and elsewhere you'll get many reports of what kind of temps people see with it.

You may however be in for a rude surprise whenever you next clean your loop... I would expect that your blocks will become gunked up with whatever that fluid was in the glowstick. Over time that kind of stuff tends to precipitate out. Also, it's probably unlikely, but there's no guarantee that whatever it is will NOT react negatively with the copper/nickel/brass in your loop. Stick with distilled and colored UV tubing, or if you really want to color the fluid, use something reputable like Mayhem's dyes.

Ha yea i figure, why LC if your not going to use it biggrin.gif , the Q9550 is volt hungry over 4ghz. I will run a benchmark tonight with the stock clock/voltage. As for the glow stick fluid, its uv reactive and non-destructive to plastic; loop is still 98% distilled water.

Thanks for the info, will have to verify if anyone else has +10 deg C variation between cores. Maybe core0 is used for some additional process.
The dye in glowsticks is Flurophore, same stuff in uv dye. There is also a hydrogen peroxide reaction that is neutralized after the glow-stick stops emitting light. Not too worried about the copper, sort of interested to see what happens when it heats up though.

Reset the clock to factory, performed load test, then re-clocked to 4.25 ghz 1.6600Vcore
Ambient temp is 77F (25c)

your overclocked loaded temps dont look too bad 41.25 delta.. thats a hell of a clock too. from 2666 to 4250

Thanks biggrin.gif
The one core is still a little hotter, but things seem to be balancing out a bit. Maybe the thermal paste just needed to cure for a bit.

Wow that's a pretty impressive overclock for that chip. Props to you for getting it that high. Temperatures seem about normal. Congratulations! biggrin.gif

Just be careful with the glow stick fluid. Even though it's the same stuff used in UV, it could still be a different viscosity, and composition than pre-mixed fluids. If I were you, I'd spend a couple extra bucks and purchase actual PC fluid with antimicrobials and anticorrosives already mixed in, namely Primochill. If you're up for UV Green, I've had great results with Swiftech HydrX. DON'T use Feser One crap. That stuff will clog up your blocks in no time. A good coolant like Primochill doesn't need to be changed all too often, so it's not like you're throwing money away.

Good luck with your future endeavors

Oddly, reversing the loop to the "correct" direction, and using distilled water actually increased temperatures slightly (same time during benchmark run, same 81 degree ambient temperature). Also, redoing the thermal paste, did not solve the 1-hot core problem =\

hey man wonderful job on the cleanup looks much better than before. flipping the radiator and decreasing your lengths was a good call. I would try the spreading method with the business card. I never like the rice grain method myself. I always have consistent temps by spreading it. remember the idea is to transfer heat from the cpu to the waterblock not to block it with excessive amounts of paste. I like it much better than your original post:thumb:

I have no first hand experience with those chips, but I have heard many times that they have internal thermal probes/sensors that are quite prone to getting "stuck". If your CPU is reporting such variances between one core vs the other 3, I would look into this. I have heard that it can be fixed, and also that it can't be fixed...
