Land Grid Array (LGA) 1155 CPUs are not compatible with LGA 1150 sockets. Because, LGA 1155 socket is for Intel microprocessors which are based on Sandy Bridge (2nd generation, 32nm) and Ivy Bridge (3rd generation, 22nm) architectures, and LGA 1150 socket is for 4th generation Intel processors.
If you want to fit an 1155 CPU in an 1150 socket, it will be a complete disaster. Different generations of CPUs are compatible with different sockets. But in some rare cases, CPU companies upgrade the CPUs but not the sockets. In that case, the CPU will support multiple numbers of sockets.
LGA 1155 CPU Socket in 1150 Socket of Motherboard – Consequences
Usually, a processor uses a specific socket to operate. But it does not mean that the CPU will run in any of those sockets. Because motherboards matter a lot here. In this case, 1155 CPUs will not work in 1150 sockets as 1155 and 1150 have different amounts of pins.
LGA 1150 socket is for CPUs built on Haswell microarchitecture. For example, Intel Core i5-4570, Core i3-4150, etc. will support an 1150 socket. But LGA 1155 CPUs like Intel Core i3-2120, Core i7-3770, etc. are for 1155 sockets that can not operate in the 1150 motherboard.
So, you can not fit a CPU in the wrong socket. It will not fit in. If you manage to cram an 1155 CPU in an 1150 socket, it will not work. Even, the CPU may damage due to wrong pin connections. Sometimes you may damage the pins of the extra pressure on the CPU.
LGA 1155 and 1150 Socket: Compatible CPUs
Here, you will find out the CPU compatibility with both of the sockets. Have a look at them –
Compatible Motherboards CPUs with LGA 1155 Motherboard
Some 1155 motherboards are –
- ASUS P8Z77-V PRO-LGA
- Intel Desktop Board DH67BLB3 Media Series
- Zotac Z68ITX-B-E
- Genuine Dell OPTIPLEX 390 Mini-ATX

Compatible Motherboards CPUs with LGA 1150 Motherboard
Some 1150 motherboards are –
- Gigabyte GA-Z97X-UD3H-BK
- ASUS Micro ATX DDR3 1600 B85M-G
- ASRock ATX DDR3 1333 FATAL1TY Z97 Killer
- MSI H81M-P33
And some 1150 compatible CPUs are –

Frequently Asked Questions (FAQs)
Is there any adapter to fit the 1155 CPU socket in the 1150 socket?
No, there is no adapter to fit an 1155 CPU onto an LGA 1150 motherboard. In fact, it does not work in that way. As every kind of socket has a different number of pins, it will not fit with the wrong CPU. Even if there was an adapter, some pins would have been disconnected.
Is LGA 1151 the same as LGA 1150?
No. The LGA 1151 is a replacement for the LGA 1150. (known as Socket H3). The Intel Skylake and Kaby Lake CPU microarchitectures are supported by the Intel microprocessors compatible LGA 1151 socket.
Conclusion
There is no way to place an LGA 1155 CPU in the 1150 socket. If you want to keep the motherboard, you should buy a compatible CPU and if you want to keep the CPU, you have to buy a compatible motherboard.
