Moar experimenting timez!
One issue that might make me OCD, is heat soak. I hate it on my turbo'ed cars, and I sure as hell hate it on my computers. Yeah, im loving the low idle temp and the very low full CPU load temps, but I really hate it when my pc is running for hours, and I keep our house temp at 75f in the summer to save power, that my processor will heat soak and stay @ 33-34c depending on how high the max. load temp was prior, how warm it's it is outside of the case(My wife's SLIed 550 Ti's pushes a lot of heat under our desks when she is gaming), and how long my computer has been running. I have soo many ideas to try out but very little resource and I am trying to keep this as cheap as possible. So far my totals for this project is 130 dollars including the coolant. I dont count my component upgrades in this because I was going to buy the motherboard and CPU to update my rig anyways.
All of this was just ideas, until something bad happened that I can benefit from...
I have had this drink cooler for years now (yes, I put a micro switch on the bottom so I can leave it plugged into my USB, and just simply put it on its side to turn it off), and the fan inside finally died, so now I have a 5v peltier cooler to play with!! My idea is to combat heatsoak. I refuse to even think of putting it directly on any chip, due to the amount of condensation that I learned first had brings, I just cant risk it with my budget, so I was thinking of chilling the coolant just enough to fight heat soak. However, I do not want to cut up my pretty XSPC reservoir, so for now its going to be a pre-cooler to my CPU.
So this is what my first experiment is done: I took about 4-5 inches of aluminum pipe, bent it in an "S" shape, (I tried to make a dual pipe, but I dont have anything to couple the two pipes into one feed and lead), flattened it in a specific pattern with pliers just enough to have good flow but fit flush on the cooler, and used the original cooling surface to sandwich it all together. Then I simply just removed my pre-bent pump to CPU pipe, and bent up a new route to the CPU with the peltier cooler in the series.
So far I have experimented on running 12v in the peltier, yes it rapidly cooled the coolant, but for about a minute until it got warm, due to the crappy 80mm scrap fan cooling the hotside. 5v does the job but not as quick, yet it will keep cooling to the lowest possible that my cheap block can do, 28c.
It doesnt get it any colder than that even though the coolant itself is around 60F or 15-17c after about 30 minutes coming down from a 59c of an hour stress test from the usual cpu and ambient temp adjusted cooolant temps. Just getting a 17c coolant in the reservoir gives me hope for my ideas.
