Getting hot temps under load test on my core i5 4670k

dazkyl · Nov 22, 2013

Mobo : asrock extreme 6 z87
cooler : v6gt coolermaster

i oced my cpu from stock to 4.4ghz with 1.250voltage.

average idle temp is 43degrees and underload with prime95 it jumped to 98degrees.

How it this even possible ? Those are very high temps for such a decent aftermarket cooler.

Multiplier is x44 and cache mult is 35 as said in this topic :

Why are those temps high ? What should i do ? i built this pc yesterday so i think there is no need to reapply thermpaste.

If thermal paste is applied correctly and the cooler is mounted properly, then you just might have a chip that OCs like this. I have a friend that can't get his chip over 4.2 without getting thermal problems, and he's running a closed water loop. My other friend has a Haswell chip he has OC'd to 4.6 with a Hyper EVO 212 and it doesn't jump over 80C. So just because someone else can get theirs to a certain point doesn't mean your chip will do the same. So you just might have a chip that doesn't OC very well. That being said, having an 24/7 OC at 4.2 or whatever you are able to reach with safe thermals (which 98C is not lol), will be pretty much the same performance wise as 4.4. A few tenths aren't gonna make or break your experience.

The only reason you might need to reapply would be if you installed it improperly I don't know how much more you'll get out of it if any by remounting/adding better paste, but I wouldn't leave it at 4.4ghz if it gets that hot.

Supahos :

Should i lower it from 4.4 to 4.2 and check temps ? maybe i try re-seating cpu cooler tomorrow as well ?

Supahos · Nov 22, 2013

I would drop it to 4.2 right now, and then reseat, and try for 4.4 again tomorrow after the reseat, you don't want that thing anywhere near 98C It won't hurt it instantly but that isn't good long term.

Supahos :

I will drop it to 4.2 now and try the rest tomorrow first thing in the morning. What's a start safe voltage for 4.2 ?

Supahos · Nov 22, 2013

I wouldn't think you would need to be much over stock voltage, maybe best idea, is reset everything to stock, and see how high you can go without moving it.

Supahos :

Any idea what's the stock voltage for the 4670k?

Well both your idle and max temps are high. I would think normals would be in the mid 30's C under idle and max out in the mid 70's C. What type of case are you using and how many fans are in it. What are the room temps that you are in? Make sure your fans are all blowing the correct way too.

Case is cm storm stryker. Got 1 top exhausting 200mm fan , 140mm exhaust rear fan , 2 side intake fans u 2 bottom intake fans.

Room temp is pretty cool.

Supahos :

I entered the bios and changed cpu input voltage from offset to fixed and the ammount was 1.900v. Is that normal ?

EDIT : atm running at 4.2ghz with 42degrees idle temp. Core voltage showing in cpu-z is 1.220v
