Gigabyte Owners whats TMPIN2 Sensor?

In CPUID HwMonitor whats TMPIN2? I know TMPIN0 is motherboard sensor and TMPIN1 is cpu socket.

TMPIN2 runs 70-77c idle and 89c prime95 load. Should I be worried?

On mine that's the northbridge. That sounds awfully hot too.

I think its the nb too. When I touch the heatsink its HOT! TMPIN2 has always stated temps that high. Yesterday when I installed my antec 620 I took the nb heatsink off and cleaned the heatsink and nb chip and put some thermal paste on it and used some screws instead of pushpins. But its still hot as hell. Guess I need a copper heatsink huh?

Well I don't have experience with that board but if it's still running hot you might want to double check it's got a secure connection. Also a small fan would definitely help.

My nb used to idle in the low to mid 50s, I added a second fan to my cpu cooler and another intake fan and that little extra airflow lowered my temps to low to mid 40s.

Will that fit? I was thinking about taking some heatsinks off of some old mobo's and trying those but they are all square... I dont think the holes will match up. On my gigabyte board the heatsink is rectangular and I believe the screw holes are further apart. Though I haven't measured. Guess I should just to be 100%.

TMPIN2 on Gigabyte boards is the VRMs/MOSFETs and they are overheating!

Running a 125W x4 on a 3+1 phase power board with known problems, with OC, you should be extremely worried. Gigabyte stopped rating their 3+1 boards (at least recent ones) 125W compatible and max em out at 95W because they're really not 125W capable!
You sir need a new board before catastrophe occurs!

Your northbridge does not run hot on AMD platforms unless cooling is improperly mounted - but TMPIN2 is not the northbridge sensor, it is VRMs on Gigabyte AMD boards usually.

Well I think I believe the reading because the heatsink is very hot. Speedfan has the same temps also. If i leave my finger on there for more than a second it will burn.

I tried measuring... very difficult without removing the mobo but im lazy. I got something like 80mm. I also tried measuring the length and width and then using Pythagorean therom and got 81.54mm.

TMPIN1 is the northbridge on Gigabyte boards.... your max on that is 55C, and 55C definitely feels hot on passively-cooled devices, I've felt my Biostar 785G northbridge chipset before (it loads also around 55C) and it feels quite hot and I can't put my finger on it for more than a second. At 55C your northbridge is safe.

TMPIN2 which is approaching 89C is the VRMs and they are definitely overheating to unsafe levels. This is happening due to the power consumption of the processor you use and phase count; you need a new motherboard to safely support that processor esp. with OC, or you could end up with fried fets and a massive paperweight with burn marks instead of a mobo.

Ya I'm aware it's not a great idea on this board but I do what I can with what I have... This is only board I've got. I'm in the process of buying some enzotech mos-c1 and mos-c10 for chokes.

I'm aware of the risk. If it blows it blows... At least I had fun doing it

I really don't think heatsinks will cut it, 3+1 phase power really isn't built for 125W processors. I knew a couple of people on ASUS 3+1 boards using 125W processors on them; the OCP (VRM anti-fail) activated way too often at load, throttling the processor and reducing performance, because the VRMs overheated and overloaded. This was with these CPUs at stock speed, on the stock cooler (so VRMs are even getting some air cooling).

New Gigabyte boards with the exact same VRM design are not being rated 125W ready. Their lower-end 3+1 design with cheap 3-transistor fets and also does not feature OCP, so they are actually known to fail, nearly as much as most MSI 3+1/4+1 boards. This is why you really must invest in a new board! Or begin undervolting (underclocking?) if you wish to remain on the current board.

I believe I may have reversed TMPIN0 and TMPIN1 then. The "motherboard" value is northbridge chipset. TMPIN2 is the VRMs on Gigabyte boards. At these temps, 90C load (as expected due to 3+1 phase + 125W processor) they are way too hot to be safe. I use an 8+2 phase board and your VRM's idle temps of 69C are slightly higher (2C) than my VRM load temps.

Sucks to be me

I'm still going to get the enzotechs but if my board blows I can always use them on the next board. So what do you consider max safe vrm load temp?

Thanks for all the help:applaud:
 
#17 ·
Alright, but be careful. VRM fails (not necessarily always explosions) are capable of taking out other things; though it happens rarely, if it does happen it is usually the PSU (and by extension other things).
Optimally the VRM load temp should be around same as CPU or 10-15 deg higher, no more than 75C over long periods of time (as a general estimate)

Getting those heatsinks isn't going to help AT ALL.

Kill that board, kill it with fire now. Before it does itself.

I had that same EXACT board, with a newer revision even. Athlon II x4, 95w quad. Bone stock EVERYTHING.

The board LITERALLY caught on fire at bone stock. Took out my CPU, RAM, and PSU with it.

I'm dead serious on it. Get rid of that board asap. I'm not the only person on this forum that had that board smoke either....with low wattage CPU's mind you.

Yes IXcrispyXI your temps appear well within the limit.
Looks like pioneerisloud's post justifies a lot, I could've sworn he had experience with this same board before so I had pointed him to this thread.

I have the 990FXA-UD3 and the NB gets WAY too hawt. (65c AFTER I slapped a fan on it).

TMPIN2 is the NB on the newer boards if I'm not mistaken, but previous to about 800 series TMPIN2 described the VRMs/MOSFETs.

Wish they still DID represent the VRM's/Mofsets. :/
