Typical radiator temp? 3d printed bracket

[Linkinworm]

So I've got this 3d printed bracket made for my radiator to allow it to be offset inside the case. Since the Corsair 220t is pretty cramped and I didn't like the drop offset mount I had installed before.

 

But now I'm worried that the radiator might get hot enough to melt the plastic and I don't want either the rad to just drop or end up with a plastic mess.

 

I had it made with petg and it looks like it was 100% infill as I had to grind some down and the inside looks solid

 

Does anyone know what the typical temps for a radiator to get are? I read petg could melt between 50 and 80c? I was thinking maybe changing the setup to a pull rather than push so that the bracket would get blasted by the fans directly. Likely doesn't matter that much though?

 

I'm using a artic freezer 2 with a 14600k. And I know I can hit like 80c on the CPU under 100% benchmark load typical about 50 under gaming conditions

 

Attached some images if that helps with determination of the size of the bracket to heat ratio or what ever.

Hi buddy,

 

While I've never measured the temp of a rad directly, I like to fit a Barrowch OLED Flow Meter and Coolant Thermometer to most of my loops and it tends to report 40ish C most of the time. 45C if its a hot summers day but I live in Scotland and we don't really have summers lol. I would also say, it takes quite a while for the coolant to creep up to that.

 

Assuming my knowledge of thermodynamics is correct, the rad(s) should only be the same or less.

 

To keep temps under control, have you undervolted your 14600k? I managed to get my 13600k to all-core 5.4P / 4.4E at 1.2v and my temps at full load hover around 70c.

I don't think Push / Pull drastically increases cooling performance. I think most people would argue that a thicker rad and more fins wins hands-down.

 

Push-pull is great for quieter environments as you can move air more efficiently at lower rpms. It also looks pretty cool if your into RGB and have some nice Lian-Li infinity fans or Phantec D30s

The aio would need to BOIL before the petg will start deforming a bit. So if it starts doing that you have WAAAAY bigger problems than petg deforming

 

Dont worry they can't get that hot in a pc. So this is a non worry

push is better than pull.   push/pull can give u 2-3c

and radiators front mounted(where they shoud be) can give u 6-10c

Yeah you should never see more than 40-50°C, no problem for PETG.

It will melt, then drip on your components, damaging them. Dont do that.

 

No, nothing will happen, radiators stay pretty cool, and its very rare for them to go above 50c, which is not enough to melt plastic at all. Fans are plastic. Have you ever seen fans melt from touching a radiator/heatsink when under load? No.

Not don't much voltage wise yet. Ironically the day I went to mess around I updated my bios because gigabyte release an update for disabling cep protection or something like that and now my bios just crashes when I click anything

For reference: this rack mounted PLA print is keeping up the weight of two 360 radiators since 2018:

It has bent a bit over the years because it had to printed in two parts, but still holding after 6 years. So i think your printed rad mount is fine.

push pull is like maybe 1 c drop.

That is a non-sequitur. Just because they are made of plastic doesn't mean its the same kind.

It is fan dependent, though, but if the pump is amazing, even strong fans won't help much.

flow has nothing to do with the fan air flow... the more water flow the lower temps whats your point?

faster fans more air flow also lower temps. but push pull dose not make the air faster...and at best 1c difference

 

buying a faster fan or fan with more flow will lower temps

buying a pump thats faster also lower temps...

buying more rads also lowers temps...

buying rad fans are good at pushing air thow the rad more being better for rads vs case fans.

more cpu fins lower temps

using copper vs aluminum will also lower temps
