Custom 20 dollar loop high temp issues.

[Kruelism]

So one day i decided to pull out an older Intel 1156 cpu and motherboard, still has high temps still around 50s-60s C abit high. ran down to the hardware store and picked up some 5 dollar tubing and some other things.
Temps start to idle about 45C. when at the 3 Ghz Overclock. The pump is a inline fuel pump *for a car i know lol* since i have a box of 20-30 of them sitting around >.>
CPU cooler has direct contact pipes that i cut the tops off and stuck a tube on them directing flow though each one of them.

Thought it might be the ancient stock intel thermal paste in the cpu so i delided it and same issues.
The temps spike up by 1C every few seconds when cpu stress testing.

is there a radiator?

Yes there is.

I seriously doubt it's old thermal paste being your issue

 

Your flow is mangled, heat pipes are specific purpose use.  They aren't meant for flowing coolant like that.

 

Cool try but now you know.

... what the fuck?

Actually the flow could be to much it blew the hose off the radiator that is after the cpu.

You mean there is a restriction causing too much pressure.  You don't have enough flow to cool the CPU, is what I mean.

are you literally just running water through heatpipes??? and expecting performance??? what have you done man...

[mxk]

lmao what is this thing? yeah it's probably the flow, as jstudrawa already mentioned.

Well the pump i used is about 200 GPH so it's got some pressure and had to reduce it down abit with a fuse to stop it from blowing the hoses off the radiator and other sections. The cpu cooler has larger heat pipes than most common coolers have from comparison with what i have and seen.

No not performance it's for the fun of it to see how far i can push it for less than 20 bucks.

When you get bored and have 40+ old computers sitting around lol.

well you ruined the cooler that was on there if you didnt know as the heatpipes are now wrecked. Anyway if you want more performance get a block off alibaba or something, should only be a couple of dollars

Well duhh lmfao. If i was going to do that i would have just bought one this was just pure boredom and why not. This isnt an every day machine this it's been in my basement the past 8 years lets mess around machine.

This may come off rude (it's not my intention if it does seem rude), but why are you asking if its a "duh" situation? If it was obvious to you what the issues were then maybe thats why the temps were going up.

You know what? Loop like this is perfect for April 1st

Well it's purely just attempting to see how much i can push out of it before pulling out the liquid nitrogen in the future. Wanted to see if any one else has "had" these issues the cpu it self runs hot even with any other cooler from what i have noticed no high/low spots on the cpu it self that would cause this issue.

Tbh it was made on the 1st lmfao

I've always wanted to do this actually, (currently staring at an unused hyper 212). Ignoring the fact that is not what it was designed for, which is lost on some people, let's try and troubleshoot the problems. First idea, see if you and run the coolant through the pipes in parallel, this is not going to be easy, you will have to find a 4 output manifold and or make one, but it should improve heat transfer a little, and more importantly the uniformity of the transfer. Second idea, if you have a thermocouple, check the temp of the air cooler, maybe some\a lot of the heat is not getting to the water rad and adding a fan to the air cooler will help. 3, if you do have a the thermocouple check the temps of the water going in and coming out of the air cooler, now they wont raise much, ie if you cpu is 50C the water will not be 50c, but this will tell you how efficient the heat transfer is. If the temp goes up by 10-15C(just a guess here) or so you are getting good heat transfer and your issue is cooling that back down with the rad. If it only goes up a few C then your issue is the transfer of heat from the CPU to the water, this could be from cpu to cooler transfer or cooler to water transfer. 

 

Hope this gives you an idea!

Yeah i found out the issue was 100% heat transferring from the cpu to the heat sink. I solved the over heating issues and was able to overclock it to 5.4 Ghz before the system started crashing. i obtained this by directing putting a copper plate on the cpu die to the cooler instead of the standard ihs. This was done out in my garage and it's still winter where i'm at so it's still cold outside was running about 50c with max of 65c with the 5.4 Ghz overclock. If it was summer i would have more than likely only obtained about 4.7 Ghz at max. Now the cpu cooler i used the heat pipes are larger than most heat pipes. That is why i picked the cooler out of many other ones i have in my "spare heat sink box"

[kohh]

It does sound like a flow issue. Maybe try a cooler with more heat pipes.
Although at that point you might as well just give in and get a block from alibaba or ebay.
You don't have to get a nice $5 one that has the proper socket mounts or anything.
You can still just get the $0.85 ones that people use with their peltier chips.

Awesome! I'll have to give this a try when I'm bored one day.
