Just put a build together this evening,the 2 main parts being a G1820 and the $60 MSI gt 740 from Newegg.

Big issue is that the MSI GT 740 is hitting upwards of 91 cel on load.I did about 15 reapplications of AS5 and this is the best i can do.I have done it before on a 7850 so i know it isn't the application here.Single solid aluminum piece here held up on 4 tension screws typical of a gpu.

Could it possibly be a voltage issue?MSI AB issue?i ramped the fan to 100% and got a desk fan blowing directly on it and it loads up to 88 cel but it can hit 91cel if i remove the desk fan.Cover off my pc or on it loads just the same pretty much.

Anyone else having issues with this particular card?

105c is the throttle temperature, I believe. So while 90C is hot, it's nowhere near too hot under a heavy load.

EDIT: NV lists 105C as a general gpu "throttle temp", and gives 98C as the GT740 "max temp".

If you are using Furmark or the like to apply an artificial heavy load, those high temps are not related to real world use.

15 times? That's nuts! :eek:

Make sure the airflow through the case is good.

Front fan blowing into the case, rear fan pulling air out the back of the case, with a good flow through.

It appears the cooler just likes to hit 91 cel.My desk fan hits at least 150cfm and i had it hitting the gpu directly.The card just appears to like running hot unless the Bios is giving false readings to gpu-z and MSI AB?

Other reports do mention high fan noise on this card but some people do get lemons even on the best or worst of cards.

WOT with a 98% load and even the Stress Tester with GPU-Z which hits 99%.

VDDC according to MSI AB is 1.0120v and that either idle or load.

I actually wouldn't worry about 90C at max load. How often will you be at max load for long periods in normal use?

Furmark will probably make it throttle.

Generally, throttling is what I look for. If it's not throttling in normal use, then it's okay.

Your GT740 appears to be staying well below throttling at 99% load.

It does throttle occasionally down to 503mhz from 1006mhz if it sits at 91cel long enough but i dropped a couple settings in WOT and i'm not even touching above 86 cel atm as gpu usage is a bit lower.

Keeping the usage under 95% or so it seems the card won't even touch 90cel.I never seen a card hit these temps before and i wouldn't know what impact it could have if any long term or if its even safe.

Temp during Heaven run?

Also, 3rd party sellers on NewEgg asking $180 for this GT 740, lol. Why does NewEgg allow that, it looks horrible.

Well, with what you just said about it actually throttling, I would look to return or exchange/RMA the card, just to be sure you don't have a lemon.

It also sounds like you actually need a bit more card, like a GTX750.

Wanting this as a temporary card anyways,i didn't expect the world for $60.For $60 i figured a badly binned locked down non overclockable card or the cheapest possible cooler.Slapping some GELID GC-Extreme on it later on but overall i got no issues with the card at the moment considering its still running within the specs.

Running settings that enable a smooth comfortable 60+ fps frame rate,the GT 740 honestly is being bottlenecked by the G1820 by a considerable bit if it isn't overkill for 1024x768.Means low gpu usage period for the moment and lower temps.:thumbsup:

Going to slap in a 750 ti later on,then a brand new 900p monitor.The 768p is my only spare for the moment outside of a headache inducing 1280x1024 60hz 17'' crt.

Does it have a similar cooler to this?

If so I've just installed a MSI 750TI with the same or similar cooler and temps don't reach anywhere near this. Never seen them go above 60c, but then the most I've tested it with is 3Dmark11.

It could be a problem with the Tim or the fitting of the cooler. For example the Asus DCU II cooler developed for the 780 was very effective, until they used it on AMD 290's where it didn't quite fit.

Running fresh drivers and this card in my other rig,will see if the issue persists.It was maxing out at 91cel then oddly enough when i installed Evga precision the temps skyrocketed nearly immediately to 99 cel then i forced the pc off .

I think some driver bug or software issue is causing this,i will know shortly.I got some spare cheap cpu paste i will try next.Maybe the AS5 isn't agreeing with this card?It worked perfectly on a 7850 before with good results.

Same exact cooler btw on mine.

The heatsink is barely contacting the gpu i guess?I went through all the amounts from a grain of rice to slightly bigger then a pea with the thermal paste.Spread it a few times and just dropped the heatsink on with various failing results.

Finally i said f*** it all and slap on over 2 peas worthy of paste,drop the heatsink on and what do you know suddenly its maxing out about 71 cel on 99% usage in gpu-z stress test.

Only thing i got is perhaps the heatsink is barely making contact,which is requiring both oem and me to add additional paste to remedy the issue?Its just insane.It was loading over 80cel before with the oem paste but now about 71cel.

Oddly enough the gpu render test results wildly differ from Bioshock 1 results,i freaking hit 88 cel again.No matter the thermal paste application,it either loads up to 91cel or goes bonkers,gives me a low reading in one program that gives me another in a game.o_O

I'm convinced either the thermal readings are completely busted or the Bios needs updating.I repasted a few gpus before so i know it isn't that at all.

Any chance of a Bios update?

You could try just RMAing it, it doesn't sound like a simple repasting it going to help you. You could always try removing the shroud and fan and just blowing a high velocity (think AFB1212SHE) fan at it if you have one to see if the temps go way down, but that's a decent bit of work for a $60 card.

Going to lock down vsync on the more demanding games,lower gpu usage and limp on by till i drop in a respectable 750 ti in here.I intended on this gpu being temporary and more so even now.:thumbsup:I will pretend its just a reference 290x,the noise surely is a good analogy.

I will try the shroud idea,i got my doubts but what the heck.

First game i played today on this that ran my gpu usage actually to 98% and 91 cel at 1280x800 is Bioshock 1,the G1820 just bottlenecks the gpu in all my other games LOL.I am lucky to hit 70% usage in the more recent of games.

I was more or less playing around with DSR and higher resolutions when i noticed this issue of high temps.

I fixed it!:D I was right about the heatsink possibly being the issue and of course it was.

They put these o-ring type sticker deals where the mounting holes go,maybe in case you go chuck norris and strip the pcb with the screws?I removed all 8 of them from each side of the pcb and sure enough bingo!Loading at 72 cel now.It wasn't getting proper firm contact period before.....

I will remove a bit of the gpu paste,temps should improve a bit i hope.:)

Hit a cheap coin with a belt sander to smooth out both sides, then wedge it between the gpu and heatsink with paste on both sides, haha.

You can actually buy copper shivs for very cheap on ebay for almost this purpose, usually they are meant for secondary laptop chips that don't quite touch the cooling system.

Temps are a healthy 69cel,won't go above.I ran out of AS5 messing around with this gpu so i cleaned up the gpu a bit and put the rest of what i had on there.

Guessing perhaps there was a machining issue with my heatsink and it fall short maybe half a mm or so from official specifications on its thickness causing the relentless overheating.stacking 2 of those o-rings its thicker then the cardboard box material that holds a 12 pack of soda pop.Thats the space i had basically between the gpu and heatsink.D:

None the less if their quality control is this bad,it's officially my last purchase from them.Had issues with the fans on a TF3 7850 going out before then this.Nothing but issues with their motherboards.

For $60 i guess its still not bad but damn it,i got a headache from this freaking thing.:eek:
