Temperature problems

I'll have a look later then when my cooler arrives. Thanks for the help so far guys

I'll post some pics up of the CPU as not really sure how to tell personally

You'll be looking at the adhesive between the heat spreader and the green board. It should be quite a thick black adhesive. The heat spreader shouldn't be wonky either.

Let's just hope if it has been delidded they didn't stick it down with super glue as I've read some people do.
 
Yeah some superglue it
Some just do a dot of superglue each corner not all way around
Would have thought the seller might have mentioned it if its been done
Guess you could ask the seller?
Assuming they're still a forum member
 
Yeah have pinged him a message. Not an issue if it's been delidded without me knowing, guess I should have asked before!
 
If it's not been delidded then it's more than likely that the crap Intel thermal paste has "gone off". When I got my old 4790k the temps were just ridiculous so I decided to delid it. When I got the IHS off I found that the thermal paste had set like concrete. I cleaned it up and put some liquid metal between the die and IHS and then refitted the IHS using liquid gasket on the inside edge of the IHS and not on the surface that contacts the IHS so that I could get as good heat transfer as I possibly could. Between the IHS and block I stuck with Kryonaught. Doing that knocked a whopping 25 degrees C off the load temps.

Yeah I had thought so
I don't have a vice or anything at home though so it will be v difficult for me to delid at home, and that I have no experience doing it!
 
Asked the gent I bought it off the MM - he said it hasn't been delidded to his knowledge so cooler is next on my list to try
 
Sounds like the pump might be on the way out. My H100 & 4670K did similar after a few years. Pump RPM showed fine, but coolant wasn't circulating. CPU would start throttling within a few minutes of booting up.

Went back to an old air cooler and it worked fine.

Stick a request in the wanted section of the MM to see if somebody will lend you a delidding kit. I did that and was loaned a kit and it took 30 seconds to delid mine. You can't mess it up with one of the proper kits. I did my old 4670k in a vice and that was a real sphincter clenching moment hitting a cpu with a hammer to remove the lid!! You can do it with two pieces of wood as well.
 
It's quite hard to tell, but on the second pic the blob at the front between the heat spreader and green board looks suspiciously like super glue. Although it could be the flash that is giving it that slight translucent look and it's just thermal paste.

There should only be black sealant holding it down so if there is anything else it's been delidded at some point
 
Sounds like it might be more than bad TIM print not transfering heat, but just to be sure, you found a good TIM print when you removed the test cooler? While TIM is way better than no TIM, it still still not even close to direct metal to metal contact. TIM has a tranfer rating of 3-12W/m K. Copper is rated 400W/m K. Air is rated 0.024W/m K. We want TIM to only be filling irregularities where there is not direct contact between surfaces an not forming a layer of TIM between contact surfaces.
