Extremely bad temps after delid | i7 7700k

[Eliel]

Hi there. My system was running quite hot, over 85°C w/ stock freqs and voltages. I'm running it with a Deepcool Captain 240ex aio, ID Cooling Frost X25 thermal paste (10.5w/mk), and my beloved Z270E Asus Strix.

I delidded the CPU recently, because i tought that the problem was the intel's tooth paste, but it wasnt. After delidding, my temps idle went from 33°C to 40, and under load from 85 to 90/91. I really don't understand why, everything is OK, thermal paste evenly applied on the processor in both sides, tested relidded and w/o gluing the cpu back again and the same results... I know delidding with thermal paste is not the best, but it works, this thermal paste is better than AS5, MX4, and others. My AIO is working fine I think, pump is running at 2300rpm (ok), its mounted properly and i dont know what's happening! Help! i dont want to run it like it's rn, i'm about to explode. Ty!

Why would you bother delidding a "checks watch" 6 year old cpu?

The 7700k is a hot CPU. Don't delid unless you are going to use liquid metal. I have first hand experience with delidding and a 7700k, and tried thermal pastes, liquid metal is needed if you want improved temps.

Well, this CPU is well known as having bad temps due the intel's TIM, and having 85°C with a 240mm aio and good paste with STOCK freqs it's not pretty nice, it's my main system, i live in a country that it's hard to get the latest hardware, and i like my pc, i want the best for it.

To make it run cooler. 7700Ks benefit a lot from a delid. 

 

For OP, I'm not terribly familiar with delidding myself, have only used chips delidded by the previous owner (6700K that went in a rig for a friend, and the 7980XE I use now). Always using liquid metal as it's both very good at transferring heat, and extremely thin so minimal space between die and IHS. Are you sure the paste isn't so thick it ends up leaving a taller layer of TIM? Or else residue on the chip itself under the IHS borders, spacing it slightly away from the die so bad mounting pressure.

If you wanted the best for it you wouldn't have delidded it. If you want to drop temps, you are going to need something like thermal grizzly conductonaut. Although you can destroy your whole system if you mess that part up

Well, maybe i'll have to buy LM... Expensive AF, (at least here).

It's really sad, but i still want to know whats happening because the paste i used is NOT worst than the intel's tim, and i still have worse temps

No residue, and i think that there's not a lot of distance between die and ihs, i used a relid tool, and also i mounted the cpu without glue on the socket, with no improvement

Let me guess. Brazil? Brazil is infamous for it's expensive af PC hardware

I want the best i can buy ...

But i'll try liquid metal at the end of this month, (because it's when it will arrive if i buy it today).

Almost, Argentina.

The 2nd poorest country in America

If I lived in one of those countries, I would use a steam deck lol. The prices are INSANE

LM may just be the only stuff that works then

 

I hate working with it because it can kill hardware if you aren't careful (it will form tiny balls and try to roll away), but if you're careful you'll be fine, CPU seals back up so it doesn't cause any trouble once the delid/re-TIM process is done.

Well, imagine; i earn 260 US dollars a month (a decent pay) and delidding with liquid metal will cost 33$ of those 260. IMAGINE...

I'll try to do my best, i'm carefull enough to do a decent work but i hope nothing happens

I thought I had temps with paste between the die and IHS somewhere, maybe I do at home. I had this up on my webserver though:

 

 

That's not changing clocks, are voltages, that's nearly a 20 C drop from the delid and liquid metal alone.  I stuck with the Conductonaut. In fact that CPU / system is still running over 4 years later, over at my in laws. My son uses it after school. Haven't needed to touch it or redo the liquid metal yet. No change in temps.

As I'm sure you're already aware there's very little under the IHS on the 7700k. Cover those few contacts with some nail polish or something, and call it a day. Here is my old 7700k, you can see the contacts coated to keep them protected:

 

 

The ones on the outer perimeter will be outside. So not really a concern. I glued my CPU back up.

Yeah, i will need to apply LM...

Sad, but true if i want god thermals...

Do you think that my aio is performing ok? i know that using paste made the problem worse but, 85°C stock is still high

Yeah! i've watched a lot of videos already, i'll use nail polish too. Here's my i7 when i opened it up.

And here it's the system, (yeah, a RAM is missing)

You'll still need the liquid metal in my opinion. However did you get the old silicone cleaned off good? That could be hold things apart further and not helping temps. Once the bond is broken it's hard to say what happens when you stick it back together. Safest bet is to clean the old stuff off if you didn't.

Yeah i did it and really well, no signals of glue were visible, and i used a thin layer when i resealed, sadge

[thrasher_565]

if done right should get like a 30c drop...

The paste you used is worse if it has pump out issues which the stock TIM is designed to to mitigate.
