Testing for post with water block

[RichL]

Hi all,

 

I am just starting a new custom loop build (see screenshot for the goodies).  I am starting by testing the components to make sure they post - can I test for post with the water block on, without water running through it?  Or will there be insufficient cooling (or damage the water block)? Bearing in mind that it will be on for less than a minute.  I have an old intel stock cooler lying around, but can't really be bothered to put it on with new thermal paste, then take it off in the space of 5 mins (I also don't have any isopropyl handy).

 

What is everyone's opinions?

 

Thanks,

 

Rich

Put on the intel heat sink.

You DO NOT want to fry your CPU!

I don't know but I hope all goes well and good luck with the build

The new i7's doesn't come with any heatsink.

 

You are fine to post the system and alike without a heatsink on, but you really want one if the system is going to run any longer than a minute or two.

Read his post.

He has a stock intel heatsink

It is possible to let a modern CPU run a short time without any cooling, but because you have that heat sink I would put it on, even if you have to put it on without thermal paste. That's still better than nothing.

I'll put the stock on - I'm just a little lazy but no point in risking anything!  I think I've found a place I can buy IPA nearby so I'll probably go get some there and just put a little thermal paste in. I might as well flash the mob's bios before it goes in, in case anything goes wrong with that.  Apparently you can flash over the internet now, what an age we live in!

I'd very definitely use a cooler for the POST - particularly if you have to spend any length of time troubleshooting.

 

For my upcoming (Real Soon Now!) 5820K build, which will be water cooled, I bought an air cooler specifically for POSTing - I expect to re-use that cooler elsewhere in the future, but even if I don't, it's relatively cheap insurance.

Modern CPUs will throttle back and/or shutdown before any damage is done.

So you are fine to spend a few minutes getting a POST and checking in BIOS.

Just keep an eye on the temperature.

I've run my 4670k with no coolant running through my waterblock. No issues. Also ran a 4690k with no heatsink at all when testing for post on a Z87 board last week. No problems there either.

CPUs are hardier than most people think and well protected.
